In a wide range of production and processing processes of mining, refining, cement creation, chemical processing, steel processing, or refuse processing, materials such as soot and smoke and dioxins are produced during the combustion process in exhaust gas, and general particulates are also produced during the fracturing/crushing process. Retainers installed in bag type dust collectors are used for supporting filter cloths that filter such materials or general particulates so that the collection effect can be maintained when such materials or general particulates are filtered.

Features

New epoch-making venturi axes.

Two stage throttle effects

The upper external fringe with a two-stage throttle structure is effective for preventing the filter cloth from coming off.
Any of the existing filter cloth installation methods (with or without collars) is supported.

Turn down outer circumference effects

The turned-down outer circumference reinforces the entire venturi. This increases the venturi strength significantly, resulting in eliminating any damage to occur in various works done on site.

Notch Effects

The installation status of the filter cloth can be checked while the retainer is set.
The retainer can be moved up and down easily by using notches even without using handles. This enhances the workability when an inspection is conducted.

NAMITA’s triangle venturi : 

Energy Saving Type Effects

Making bypass opening with pulse jet at locations where the venturi effect can be secured increases the suction area for dust collection and decreases pressure loss. At the same time, this venturi is also equipped with the shaking-off function on the upper part of the filter cloth.

NAMI Color is a filler that developed in order to prevent castable refractories from cracking due to differential thermal expansion by making a gap between an anchor metal and a castable refractory.

Features

Indentifiable Material

Anchor metals are colored according to each anchor material. This makes it possible for customers to check the anchor material when anchors are stored or inspected after delivery, while false recognition of anchor materials is eliminated.

Indication of material identification

Notice: Able to produce conventional non-colored NAMI coat according to particular request.

Anchor metal – Heat-proof refractories for industrial furnaces: Depending on the welded portion shape, these welded anchor metals are divided into three types, type A, type B, and type C.

Features

Quick Delivery & Cost Reduction

In the pursuit of productivity enhancement, achieved mass production by introducing welding robots and standardization of welding guidelines. This resulted in achieving a quick delivery system and cost reduction.

Quality Control

In addition, thorough quality management further enhanced product homogenization and reliability.

Anchor metal – Heat-proof refractories for industrial furnaces: This type is mainly type Y of the NAMITA type as standard, while used where refractories are installed in two layers.

Features

High stability

The nut side of the divided parts is designed to connect by screws and welding. This achieves an extremely high strength reliability as a robust product to use at ease.

Anchor metal – Heat-proof refractories for industrial furnaces: Y anchors of the NAMITA type.

Type YM4 has a flat panel part, while type YM5 has undulating portions.

Features

High stability

These types are produced based on unique technique by processing round bars based on integrated molding. This achieves lightness and stable quality.

Cost Reduction

Integrated production system starting with raw material processing achieves the mass production effects both on the cost side and the delivery time side.

Easy Handing

These types have round cross sections, which is suitable to automatic welding. This feature achieves good workability and convenient welding conditions for can manufacturing.

Low Loss Rate

A round bar is the original material having a low material loss rate when compared to panel materials.

Instant Delivery System

Always ready to deliver those products made of regular materials in ordinary sizes instantaneously from stocks
