• Features

  Mini Mini Blaster is a pneumatic micro mini blaster with a tank capacity of 400mL. This blaster comes with nozzle which provides easy installation, and is suitable for prevention of adhesion of dry powder to the wall surface or for prevention of blockage in a small container.

  Suitable for elimination of minor adhesion or blockage

  Because of its small body size, Mini Mini Blaster is suitable to be installed to a small tank, hopper, chute section, etc. It is generally suitable for automating the elimination of adhesion and blockage to such an extent that lightly striking the outer surface of container eliminates the problem.。

  

  Equipped with two types of nozzles as standard

  After drilling a hole in hopper or tank, attach the injection nozzle to the pneumatic Mini Mini Blaster. Nozzles are available in two types: tank welding type and adhesion type if welding is impossible, which is friendly to the site.

  

  Installation without welding

  For the welding type of injection nozzle, the reinforced plate and socket are welded to the container and then the nozzle and body are installed form outside of tank. For the no-welding type, the reinforced plate is mounted to the outer surface of tank with adhesive agent and then the socket and body are installed form outside of tank.

  

  1. Check the injection direction with a punch mark.
  2. Perform screwing with consideration for co-rotation of nozzle.
  3. Screw the nozzle adapter to the edge face of socket.

  *If the thickness of installation section is less than the standard value, stick the reinforced plate in accordance with the table below.

  

  1. If the injection direction is fixed accurately, perform the spot welding.
  2. Check the injection direction with a punch mark.
  3. Screw the nozzle adapter until the nozzle insertion portion is pressed.
  4. Perform screwing with consideration for co-rotation of nozzle.

  Support for relay piping

  Multiple pneumatic Mini Mini Blaster can be operated simultaneously only by installing piping from the subport of tank to the tank in relay. The position where spot injection is required can by operated by one operating valve, which allows reduction in facility cost.

  Control by relay knocker control panel

  Because the operating principle is the same as pneumatic relay knocker, the operation panel lineup dedicated to pneumatic relay knocker can be used. One control panel can operate multiple knockers, which save the facility cost.
  *For the combination of flow aid system, also refer to “Flow aid equipment combination”.

  Adjustable impact force by the pressure of supply air

  In the pneumatic Mini Mini blaster series, just changing the pressure of supply air allows the impact force to be changed by the special mushroom valve (patented). The air pressure is increased if the blockage cannot be eliminated, and is decreased if the impact force is too strong.

  

  * The blue portion in the center is “mushroom valve”

   

  Various types of dedicated controllers for knockers are available

  The dedicated control panel is available for operation of Mini Mini blaster series. The control panels include the air operation controller AOC-1B type that can start operation readily without electric power, the timer control panel for solenoid valve control KSE1 type that controls the interval between impacts and the number of impacts, and the control panel HKE series, or the control panel EKE5000 with free input voltage specification from 100 to 240VAC. In addition, the fully air controlled control panel HKA5000A for explosion-proof area is available. （Option）

This product is used for the following applications:

• 01.Installation in combustion facilities in environmental recycling plant
• 02.Prevention of blockage in the positive and negative electrode storage hopper in the secondary battery material manufacturing plant
• 03.Prevention of adhesion of ceramic material in the hopper
• 04.Ejection enhancement of resin pellet
• 05.Ejection enhancement of powdered paint

• Features

  The pneumatic Mini Blaster instantly blasts the compressed air injected in the tank through solenoid valve. Using compressed air is safe and operational cost is low. Because tank is separated from driving section, maintenance is easy and durability is fully considered. This small and lightweight product is used mainly for small capacity hopper and chute.

  Multi-nozzle included as standard equipment

  The blasting type can be selected from the vertical nozzle that blasts in one direction and the radial nozzle that blasts in all directions (360 degrees). Vertical nozzle is convenient because it can be installed in multiple ways depending on the blockage situation. The nozzle construction cost is low because the nozzle, a standard accessory, can be used, and the blasting force can be adjusted by selecting the blast type and adjusting the operating pressure. Therefore, mischoice of model or wrong installation work is rare.

  

  EMB1.5

  Effect of multi-nozzle

  It is possible to change the blast direction of multi nozzle by replacing its front and back sides of multi-nozzle plate. If, for example, the pneumatic Mini Blaster does not bring the effect, the multi-nozzle setting can be changed on site, which reduces the number of changes of installation.

  

  Easy on-site installation

  Drill a hole with the same size as that of diameter of nozzle pipe on hopper or tank wall, insert the nozzle, and then do welding. This completes the installation. Easy installation and easy completion of installation reduce the installation cost. Previously, the nozzle was directly welded to the hopper, but in this model, the previous specification is changed to that in which the nozzle is pulled out and inserted with the base mounted to the target object. In addition, the nozzle tip is equipped with heat-resistant silicon O-ring to prevent the powder from leaking.

  

  Improvement of operational environment

  The use of knocker or vibrator for eliminating blockage will reduce the noise on site, allowing for the night operation. Improvement of working environment and no metallic fatigue owing to striking and vibration will increase the product efficiency. We have received a comment from a plant worker that he can hold a consultation with smaller voice that before.

  Simple structure and high durability

  All tank models adopts the stainless steel SUS304 that is resistant to rust, and has a simple structure with high durability and easy maintenance. This reduces the number of inspections and maintenance, resulting in cost reduction.

  

  Operating principle of mini blaster

  1. The diaphragm blocks the injection port with the power of solenoid valve OFF to cause the compressed air to be supplied into the tank.
  2. The supplied compressed air starts to be charged into the tank, piping, and solenoid valve. When the supplied pressure is equal to that in the tank, piping, and solenoid valve, the charge is completed.
  3. When the power of solenoid valve is turned ON, the diaphragm moves away from the injection port to cause the compressed air in the tank to be instantly injected from the injection port.

This product is used for the following applications:

• 01.Prevention of blockage in coal storage loader and hopper
• 02.Prevention of blockage in dust hopper for dust collector in waste treatment plant
• 03.Prevention of blockage in dust hopper for dust collector in waste treatment plant
• 04.Elimination of bridging of glass material
• 05.Elimination of sludge incineration ash

• Features

  Twin type pneumatic direct blaster has one tank and two injection ports. Blasting the compressed air directly into the adhesion or clogging of powder, the product has a strong destruction force like the pneumatic direct blaster and is also excellent in safety. It produces a synergistic effect on the powder that adheres when vibrated. *For the operating principle of air relay knocker, also refer to “Operating principle of flow aid”.

  New valve mechanism improving maintenability

  For the conventional blaster, once installed in the silo or hopper, it was necessary to replace the product itself when replacing a consumable part. This took lots of hard work because the product may have been installed to a high place. By adopting the new valve mechanism in which the above disadvantage is removed, a consumable part in the valve can be easily replaced at the installation site, which improves the maintenability.

  

  All pressure tanks comply with design standards of class-2 pressure vessel

  Like the production series (pneumatic direct blaster and pneumatic twin blaster), the pressure tank for pneumatic filling is designed and manufactured in accordance with the class-2 pressure vessel standards (JIS). Although the above standards are applied to pressure tanks with capacity of 40L or more, EXEN applies the standards to all models (20L to 230L) for customers to use them safely. In consideration of maintenance, the meter is mounted outside to be able to check whether pneumatic filling is sufficient in the pressure tank.
  (standard equipment in all models)

  

  Achievement of synergetic effect via two capabilities by twin type one unit

  The injection ports located in the right and left of body blasts the air alternately. For a tough blockage, changing the second injection in a different direction than that of the first injection provides a synergetic effect. Generally, the product is installed so that combination of two or more units provides further injection effect, and has a large number of track records in the fresh concrete plant, secondary concrete product plant, plant silo of dam site.

  Cost reduction via two capabilities by twin type one unit

  One direct blaster has capabilities for two unit, which means that using multiple unit s allows significant cost reduction. The installation const is also reduced because of the number of units. The maintenance cost is also reduced because of the same reason.

  

  Safety first in factory

  Accidents have occurred continuously owing to reliance on man-powered work for eliminating blockage in silo. The blockage in silo is caused by an arching phenomenon and balance of contents. An imbalance from man-powered work causes the contents to start flowing, which will result in a large-scale accident. The pneumatic direct blaster is adopted in many sites for the purpose of preventing the above accident causing injury or death.

  

  Variable injection force by pressure regulation

  Adoption of mushroom valve method allows an injection force to be adjusted by changing the pressure of supplied air. If there is a request to make replacement for larger or smaller equipment, the issue can be solved by pressure regulation with unnecessary replacement work.

  Nitrogen gas can be used

  Nitrogen gas can be used for blast air. If the contents are flammable or likely to be exploded, nitrogen gas can be used. The safety measures for explosion proof can be secured by the blaster, which results in cost reduction. This product has a large number of proven track records in the waste disposal plant, etc.

  Dedicated nozzles are available as options

  Various types of dedicated nozzles are available, which can be chose depending on the situation of adhesion or clogging and installation location.

  

  *For manufacturing of special nozzle with heat resistance of 1000℃ or more, contact EXEN.

This product is used for the following applications:

• 01.Installation in combustion facilities in environmental recycling plant
• 02.Prevention of blockage in the positive and negative electrode storage hopper in the secondary battery material manufacturing plant
• 03.Prevention of adhesion of ceramic material in the hopper
• 04.Ejection enhancement of resin pellet
• 05.Ejection enhancement of powdered paint

• Features

  The pneumatic Mini Blaster instantly blasts the compressed air injected in the tank through solenoid valve. Using compressed air is safe and operational cost is low. Because tank is separated from driving section, maintenance is easy and durability is fully considered. This small and lightweight product is used mainly for small capacity hopper and chute.

  Multi-nozzle included as standard equipment

  The blasting type can be selected from the vertical nozzle that blasts in one direction and the radial nozzle that blasts in all directions (360 degrees). Vertical nozzle is convenient because it can be installed in multiple ways depending on the blockage situation. The nozzle construction cost is low because the nozzle, a standard accessory, can be used, and the blasting force can be adjusted by selecting the blast type and adjusting the operating pressure. Therefore, mischoice of model or wrong installation work is rare.

  

  Effect of multi-nozzle

  It is possible to change the blast direction of multi nozzle by replacing its front and back sides of multi-nozzle plate. If, for example, the pneumatic Mini Blaster does not bring the effect, the multi-nozzle setting can be changed on site, which reduces the number of changes of installation.

  

  Easy on-site installation

  Drill a hole with the same size as that of diameter of nozzle pipe on hopper or tank wall, insert the nozzle, and then do welding. This completes the installation. Easy installation and easy completion of installation reduce the installation cost. Previously, the nozzle was directly welded to the hopper, but in this model, the previous specification is changed to that in which the nozzle is pulled out and inserted with the base mounted to the target object. In addition, the nozzle tip is equipped with heat-resistant silicon O-ring to prevent the powder from leaking.

  

  Improvement of operational environment

  The use of knocker or vibrator for eliminating blockage will reduce the noise on site, allowing for the night operation. Improvement of working environment and no metallic fatigue owing to striking and vibration will increase the product efficiency. We have received a comment from a plant worker that he can hold a consultation with smaller voice that before.

  Simple structure and high durability

  All tank models adopts the stainless steel SUS304 that is resistant to rust, and has a simple structure with high durability and easy maintenance. This reduces the number of inspections and maintenance, resulting in cost reduction.

  

  Operating principle of mini blaster

  1. The diaphragm blocks the injection port with the power of solenoid valve OFF to cause the compressed air to be supplied into the tank.
  2. The supplied compressed air starts to be charged into the tank, piping, and solenoid valve. When the supplied pressure is equal to that in the tank, piping, and solenoid valve, the charge is completed.
  3. When the power of solenoid valve is turned ON, the diaphragm moves away from the injection port to cause the compressed air in the tank to be instantly injected from the injection port.

This product is used for the following applications:

• 01.Installation in combustion facilities in environmental recycling plant
• 02.Prevention of blockage in the positive and negative electrode storage hopper in the secondary battery material manufacturing plant
• 03.Prevention of adhesion of ceramic material in the hopper
• 04.Ejection enhancement of resin pellet
• 05.Ejection enhancement of powdered paint

• Features

  The pneumatic Mini Blaster instantly blasts the compressed air injected in the tank through solenoid valve. Using compressed air is safe and operational cost is low. Because tank is separated from driving section, maintenance is easy and durability is fully considered. This small and lightweight product is used mainly for small capacity hopper and chute.

  Multi-nozzle included as standard equipment

  The blasting type can be selected from the vertical nozzle that blasts in one direction and the radial nozzle that blasts in all directions (360 degrees). Vertical nozzle is convenient because it can be installed in multiple ways depending on the blockage situation. The nozzle construction cost is low because the nozzle, a standard accessory, can be used, and the blasting force can be adjusted by selecting the blast type and adjusting the operating pressure. Therefore, mischoice of model or wrong installation work is rare.

  

  Effect of multi-nozzle

  It is possible to change the blast direction of multi nozzle by replacing its front and back sides of multi-nozzle plate. If, for example, the pneumatic Mini Blaster does not bring the effect, the multi-nozzle setting can be changed on site, which reduces the number of changes of installation.

  

  Easy on-site installation

  Drill a hole with the same size as that of diameter of nozzle pipe on hopper or tank wall, insert the nozzle, and then do welding. This completes the installation. Easy installation and easy completion of installation reduce the installation cost. Previously, the nozzle was directly welded to the hopper, but in this model, the previous specification is changed to that in which the nozzle is pulled out and inserted with the base mounted to the target object. In addition, the nozzle tip is equipped with heat-resistant silicon O-ring to prevent the powder from leaking.

  

  Improvement of operational environment

  The use of knocker or vibrator for eliminating blockage will reduce the noise on site, allowing for the night operation. Improvement of working environment and no metallic fatigue owing to striking and vibration will increase the product efficiency. We have received a comment from a plant worker that he can hold a consultation with smaller voice that before.

  Simple structure and high durability

  All tank models adopts the stainless steel SUS304 that is resistant to rust, and has a simple structure with high durability and easy maintenance. This reduces the number of inspections and maintenance, resulting in cost reduction.

  

  Operating principle of mini blaster

  1. The diaphragm blocks the injection port with the power of solenoid valve OFF to cause the compressed air to be supplied into the tank.
  2. The supplied compressed air starts to be charged into the tank, piping, and solenoid valve. When the supplied pressure is equal to that in the tank, piping, and solenoid valve, the charge is completed.
  3. When the power of solenoid valve is turned ON, the diaphragm moves away from the injection port to cause the compressed air in the tank to be instantly injected from the injection port.

This product is used for the following applications:

• 01.Prevention of blockage in coal storage loader and hopper
• 02.Prevention of blockage in dust hopper for dust collector in waste treatment plant
• 03.Prevention of blockage in dust hopper for dust collector in waste treatment plant
• 04.Elimination of bridging of glass material
• 05.Elimination of sludge incineration ash

Features

Twin type pneumatic direct blaster has one tank and two injection ports. Blasting the compressed air directly into the adhesion or clogging of powder, the product has a strong destruction force like the pneumatic direct blaster and is also excellent in safety. It produces a synergistic effect on the powder that adheres when vibrated. *For the operating principle of air relay knocker, also refer to “Operating principle of flow aid”.

New valve mechanism improving maintenability

For the conventional blaster, once installed in the silo or hopper, it was necessary to replace the product itself when replacing a consumable part. This took lots of hard work because the product may have been installed to a high place. By adopting the new valve mechanism in which the above disadvantage is removed, a consumable part in the valve can be easily replaced at the installation site, which improves the maintenability.

All pressure tanks comply with design standards of class-2 pressure vessel

Like the production series (pneumatic direct blaster and pneumatic twin blaster), the pressure tank for pneumatic filling is designed and manufactured in accordance with the class-2 pressure vessel standards (JIS). Although the above standards are applied to pressure tanks with capacity of 40L or more, EXEN applies the standards to all models (20L to 230L) for customers to use them safely. In consideration of maintenance, the meter is mounted outside to be able to check whether pneumatic filling is sufficient in the pressure tank.
(standard equipment in all models)

Achievement of synergetic effect via two capabilities by twin type one unit

The injection ports located in the right and left of body blasts the air alternately. For a tough blockage, changing the second injection in a different direction than that of the first injection provides a synergetic effect. Generally, the product is installed so that combination of two or more units provides further injection effect, and has a large number of track records in the fresh concrete plant, secondary concrete product plant, plant silo of dam site.

Cost reduction via two capabilities by twin type one unit

One direct blaster has capabilities for two unit, which means that using multiple unit s allows significant cost reduction. The installation const is also reduced because of the number of units. The maintenance cost is also reduced because of the same reason.

Safety first in factory

Accidents have occurred continuously owing to reliance on man-powered work for eliminating blockage in silo. The blockage in silo is caused by an arching phenomenon and balance of contents. An imbalance from man-powered work causes the contents to start flowing, which will result in a large-scale accident. The pneumatic direct blaster is adopted in many sites for the purpose of preventing the above accident causing injury or death.

Variable injection force by pressure regulation

Adoption of mushroom valve method allows an injection force to be adjusted by changing the pressure of supplied air. If there is a request to make replacement for larger or smaller equipment, the issue can be solved by pressure regulation with unnecessary replacement work.

Nitrogen gas can be used

Nitrogen gas can be used for blast air. If the contents are flammable or likely to be exploded, nitrogen gas can be used. The safety measures for explosion proof can be secured by the blaster, which results in cost reduction. This product has a large number of proven track records in the waste disposal plant, etc.

Dedicated nozzles are available as options

Various types of dedicated nozzles are available, which can be chose depending on the situation of adhesion or clogging and installation location.

*For manufacturing of special nozzle with heat resistance of 1000℃ or more, contact EXEN.

It produces a synergistic effect on the powder that adheres when vibrated. *For the operating principle of air relay knocker, also refer to “Operating principle of flow aid”.

  New valve mechanism improving maintenability

  For the conventional blaster, once installed in the silo or hopper, it was necessary to replace the product itself when replacing a consumable part. This took lots of hard work because the product may have been installed to a high place. By adopting the new valve mechanism in which the above disadvantage is removed, a consumable part in the valve can be easily replaced at the installation site, which improves the maintenability.

  

  All pressure tanks comply with design standards of class-2 pressure vessel

  Like the production series (pneumatic direct blaster and pneumatic twin blaster), the pressure tank for pneumatic filling is designed and manufactured in accordance with the class-2 pressure vessel standards (JIS). Although the above standards are applied to pressure tanks with capacity of 40L or more, EXEN applies the standards to all models (20L to 230L) for customers to use them safely. In consideration of maintenance, the meter is mounted outside to be able to check whether pneumatic filling is sufficient in the pressure tank.
  (standard equipment in all models)

  

  Achievement of synergetic effect via two capabilities by twin type one unit

  The injection ports located in the right and left of body blasts the air alternately. For a tough blockage, changing the second injection in a different direction than that of the first injection provides a synergetic effect. Generally, the product is installed so that combination of two or more units provides further injection effect, and has a large number of track records in the fresh concrete plant, secondary concrete product plant, plant silo of dam site.

  Cost reduction via two capabilities by twin type one unit

  One direct blaster has capabilities for two unit, which means that using multiple unit s allows significant cost reduction. The installation const is also reduced because of the number of units. The maintenance cost is also reduced because of the same reason.

  

  Safety first in factory

  Accidents have occurred continuously owing to reliance on man-powered work for eliminating blockage in silo. The blockage in silo is caused by an arching phenomenon and balance of contents. An imbalance from man-powered work causes the contents to start flowing, which will result in a large-scale accident. The pneumatic direct blaster is adopted in many sites for the purpose of preventing the above accident causing injury or death.

  

  Variable injection force by pressure regulation

  Adoption of mushroom valve method allows an injection force to be adjusted by changing the pressure of supplied air. If there is a request to make replacement for larger or smaller equipment, the issue can be solved by pressure regulation with unnecessary replacement work.

  Nitrogen gas can be used

  Nitrogen gas can be used for blast air. If the contents are flammable or likely to be exploded, nitrogen gas can be used. The safety measures for explosion proof can be secured by the blaster, which results in cost reduction. This product has a large number of proven track records in the waste disposal plant, etc.

  Dedicated nozzles are available as options

  Various types of dedicated nozzles are available, which can be chose depending on the situation of adhesion or clogging and installation location.

  

  *For manufacturing of special nozzle with heat resistance of 1000℃ or more, contact EXEN.

This product is used for the following applications:

• 01.Used for hopper in which powder adheres to the wall surface in the powder plant
• 02.Prevention of blockage in the positive and negative electrode storage hopper in the secondary battery material manufacturing plant
• 03.Elimination of blockage of fish bait
• 04.Elimination of blockage of coal

• Features

  Small pneumatic soft disk blaster blasts air in 360 degrees from the disk-shaped injection port in order to eliminate adhesion of blockage of powder. As compared with the conventional disk aeration type, this employs the method for blasting the air compressed in the tank, achieving the prevention of adhesion and blockage by the loosening effect at the time of blast and instantaneous jet force.

  Installation work such as welding of injection nozzle is unnecessary

  The procedure for installing the pneumatic soft disk blaster is to drill a hole with a diameter of 35mm on the wall surface of hopper or tank, insert the attached intake pipe, and then install the soft disk inside the tank. Unlike large-size blaster, the nozzle welding is unnecessary, which reduces the construction cost. When installing the soft disc from outside of tank, drill a hole with an external diameter of 90mm or more that is larger than that of soft disk, mount the soft disk to the pressing board in advance, and then fix the pressing board to the tank with bolts.

  

  Stainless steel main parts including tank and nozzle

  The main parts of pneumatic soft disk blaster are made of corrosion-resistant stainless steel materials. Therefore, rust does not take place from inside of tank or nozzle, which allows the blaster to be used continuously in a clean status. It can be used without disfigurement even If installed outdoors.

  Heat-resistant silicon disk

  The pneumatic soft disk blaster employs the flexible disk made of silicone (soft disk) as the portion that contacts with the workpieces (contents). Silicone rubber is excellent in heat resistance, and is suitable for the small hopper that processes incineration ashes and others as a site of high temperature. （Maximum operating temperature is 150℃)
  Safety data of silicone rubber
  1.Environmental impact Not included substances subject to US EPA ’33/50 Program’ and ‘Ozone Depleting Substance Control’.
  2.We do not use lead, arsenic, chrome, cadmium, mercury, etc. as specified by heavy metal content regulation, air pollution control law, and water pollution control law.

  

  Operating principle of ESB

  1.When the three-way valve is switched to the intake side, compressed air is supplied and the mushroom valve blocks the discharge port of nozzle to cause the compressed air to flow into the tank through a gap of the flange of mushroom valve.
  2.When the three-way valve is switched to the exhaust side, the compressed air in the mushroom valve is exhausted to cause the mushroom valve to be sucked to the charging side which instantaneously blasts the compressed air in the tank through the discharge port of nozzle.
  3.The compressed air blasted from the discharge port of nozzle blasts in all directions (360 degrees) while flowing into the inner surface of soft disk.

  

  Excellent performance of soft disk

  The pneumatic soft disk separates from the wall surface for a moment when the compressed air in the tank is exhausted, and the compression air keeps being exhausted until the moment of closing, which will not cause a trouble owing to the back stream of powder. Because the operation is performed inside the hopper, the operating sound does reach outside, resulting in low noise. Moreover, soft disk is made of rubber, which does not damage the object for which the blaster is installed.

  

  

  Control by air knocker control panel

  Relay piping is supported and the operation panel lineup dedicated to relay knocker can be used. One control panel can operate multiple knockers, which save the facility cost.
  *For the combination of flow aid system, also refer to “Flow aid equipment combination”

This product is used for the following applications:

• 01.Beer manufacturer: prevention of blockage in storage silo of malt pomace
• 02.Prevention of blockage in fine sand silo
• 03.Prevention of blockage in ready-mixed concrete silo in dam site
• 04.Prevention of blockage in fractured textile storage hopper in textile factory
• 05.Elimination bridging of agrichemical/Elimination of adhesion of silica gel to wall surface

• Features

  Pneumatic direct blaster eliminates a blockage by blasting the compressed air directly to the powder that caused adhesion or clogging. It has a large destruction force and is excellent in safety. It produces an effect especially on the powder that adheres when vibrated. Its operation is easy and multiple units can be operated simultaneously. The models are available in the tank capacity of 2.5L to 230L so that selection can be made depending on the size of tank and hopper, and the blockage situation. ※For the operating principle of air relay knocker, also refer to “Operating principle of flow aid”.

  New valve mechanism improving maintenability

  For the conventional blaster, once installed in the silo or hopper, it was necessary to replace the product itself when replacing a consumable part. This took lots of hard work because the product may have been installed to a high place. By adopting the new valve mechanism in which the above disadvantage is removed, a consumable part in the valve can be easily replaced at the installation site, which improves the maintenability.

  

  All pressure tanks comply with design standards of class-2 pressure vessel

  Like the production series (pneumatic direct blaster and pneumatic twin blaster), the pressure tank for pneumatic filling is designed and manufactured in accordance with the class-2 pressure vessel standards (JIS). Although the above standards are applied to pressure tanks with capacity of 40L or more, EXEN applies the standards to all models (20L to 230L) for customers to use them safely. In consideration of maintenance, the meter is mounted outside to be able to check whether pneumatic filling is sufficient in the pressure tank.
  (standard equipment in all models)

  

  Large effect of blockage elimination

  

  Since it acts directly on the contents rather than vibrating or hitting from the outside of the container, the effect is large, so the dead stock remaining inside the silo is also less. In the case of the aggregate silo of the ready mixed concrete producer, it can be operated from the central control room, so it is adopted by many ready mixed concrete producer and is pleased.

  

  Safety first in factory

  Accidents have occurred continuously owing to reliance on man-powered work for eliminating blockage in silo. The blockage in silo is caused by an arching phenomenon and balance of contents. An imbalance from man-powered work causes the contents to start flowing, which will result in a large-scale accident. The pneumatic direct blaster is adopted in many sites for the purpose of preventing the above accident causing injury or death.

  

  Variable injection force by pressure regulation

  Adoption of mushroom valve method allows an injection force to be adjusted by changing the pressure of supplied air. If there is a request to make replacement for larger or smaller equipment, the issue can be solved by pressure regulation with unnecessary replacement work.

  Nitrogen gas can also be used

  If the contents are flammable or likely to be exploded, nitrogen gas can be used as injection air. The safety measures for explosion proof can be secured by the blaster, which results in cost reduction. This product has a large number of proven track records in the waste disposal plant, etc.

  Dedicated nozzles are available as options

  Various types of dedicated nozzles are available, which can be chose depending on the situation of adhesion or clogging and installation location.

  Installation method

  Multiple EXEN direct blasters can be remotely operated with the control panel. If only one unit is operated, it can be in either of manually or electrically.

  If the powder likely to cause dust explosion is used in the electric operation, changing the three-way valve to the explosion-proof solenoid valve allows the safe operation.

  *If multiple blasters are installed to one air supply source or the aeration is combined, be sure to install the check valves to the air supply side before the solenoid valves, respectively, to prevent abnormal injection owing to decompression on the primary side.

  

  ■Calculation of necessary amount of air
  

  V: Necessary amount of air (L/min (ANR)),  Vo: Total tank capacity (L)

  P: Operating pressure (MPa),  M: Operating cycle (min)

  Example) When using six EDB2.5-30 models at an operating pressure of 0.7MPa, at an interval of 5 minutes:

  

  Sufficiently usable with a compressor of 2.2kW.

  *Use a compressor with a discharged amount of air of 200L/min (ANR) （1.5kW） or more. If the compressor with 200L/min (ANR) or less, connect the receiver tank of 10L or more just before the three-way solenoid valve.

  

This product is used for the following applications:

• 01.Installation in combustion facilities in environmental recycling plant
• 02.Prevention of blockage in the positive and negative electrode storage hopper in the secondary battery material manufacturing plant
• 03.Prevention of adhesion of ceramic material in the hopper
• 04.Ejection enhancement of resin pellet
• 05.Ejection enhancement of powdered paint

• Features

  The pneumatic Mini Blaster instantly blasts the compressed air injected in the tank through solenoid valve. Using compressed air is safe and operational cost is low. Because tank is separated from driving section, maintenance is easy and durability is fully considered. This small and lightweight product is used mainly for small capacity hopper and chute.

  Multi-nozzle included as standard equipment

  The blasting type can be selected from the vertical nozzle that blasts in one direction and the radial nozzle that blasts in all directions (360 degrees). Vertical nozzle is convenient because it can be installed in multiple ways depending on the blockage situation. The nozzle construction cost is low because the nozzle, a standard accessory, can be used, and the blasting force can be adjusted by selecting the blast type and adjusting the operating pressure. Therefore, mischoice of model or wrong installation work is rare.

  

  Effect of multi-nozzle

  It is possible to change the blast direction of multi nozzle by replacing its front and back sides of multi-nozzle plate. If, for example, the pneumatic Mini Blaster does not bring the effect, the multi-nozzle setting can be changed on site, which reduces the number of changes of installation.

  

  Easy on-site installation

  Drill a hole with the same size as that of diameter of nozzle pipe on hopper or tank wall, insert the nozzle, and then do welding. This completes the installation. Easy installation and easy completion of installation reduce the installation cost. Previously, the nozzle was directly welded to the hopper, but in this model, the previous specification is changed to that in which the nozzle is pulled out and inserted with the base mounted to the target object. In addition, the nozzle tip is equipped with heat-resistant silicon O-ring to prevent the powder from leaking.

  

  Improvement of operational environment

  The use of knocker or vibrator for eliminating blockage will reduce the noise on site, allowing for the night operation. Improvement of working environment and no metallic fatigue owing to striking and vibration will increase the product efficiency. We have received a comment from a plant worker that he can hold a consultation with smaller voice that before.

  Simple structure and high durability

  All tank models adopts the stainless steel SUS304 that is resistant to rust, and has a simple structure with high durability and easy maintenance. This reduces the number of inspections and maintenance, resulting in cost reduction.

  

  Operating principle of mini blaster

  1. The diaphragm blocks the injection port with the power of solenoid valve OFF to cause the compressed air to be supplied into the tank.
  2. The supplied compressed air starts to be charged into the tank, piping, and solenoid valve. When the supplied pressure is equal to that in the tank, piping, and solenoid valve, the charge is completed.
  3. When the power of solenoid valve is turned ON, the diaphragm moves away from the injection port to cause the compressed air in the tank to be instantly injected from the injection port.

This product is used for the following applications:

• 01.Beer manufacturer: prevention of blockage in storage silo of malt pomace
• 02.Prevention of blockage in fine sand silo
• 03.Prevention of blockage in ready-mixed concrete silo in dam site
• 04.Prevention of blockage in fractured textile storage hopper in textile factory
• 05.Elimination bridging of agrichemical/Elimination of adhesion of silica gel to wall surface

• Features

  Pneumatic direct blaster eliminates a blockage by blasting the compressed air directly to the powder that caused adhesion or clogging. It has a large destruction force and is excellent in safety. It produces an effect especially on the powder that adheres when vibrated. Its operation is easy and multiple units can be operated simultaneously. The models are available in the tank capacity of 2.5L to 230L so that selection can be made depending on the size of tank and hopper, and the blockage situation. ※For the operating principle of air relay knocker, also refer to “Operating principle of flow aid”.

  New valve mechanism improving maintenability

  For the conventional blaster, once installed in the silo or hopper, it was necessary to replace the product itself when replacing a consumable part. This took lots of hard work because the product may have been installed to a high place. By adopting the new valve mechanism in which the above disadvantage is removed, a consumable part in the valve can be easily replaced at the installation site, which improves the maintenability.

  V: Necessary amount of air (L/min (ANR)),  Vo: Total tank capacity (L)

  P: Operating pressure (MPa),  M: Operating cycle (min)

  Example) When using six EDB2.5-30 models at an operating pressure of 0.7MPa, at an interval of 5 minutes:

  

  Sufficiently usable with a compressor of 2.2kW.

  *Use a compressor with a discharged amount of air of 200L/min (ANR) （1.5kW） or more. If the compressor with 200L/min (ANR) or less, connect the receiver tank of 10L or more just before the three-way solenoid valve.
