Made in Japan
Manufacturer: Showa Kikai Shoji

Type: Water-sealed Chain Conveyor

Features:

1. This is a scraper conveyor with a water tank, mainly used for transporting ash from coal boilers.
2. It uses SKS short-link chains, making it suitable for harsh environments.
3. Designed to transport highly abrasive materials, this conveyor offers excellent durability.
4. It features a simple yet robust structure, based on SKS’s years of experience.
5. The connection between the SKS chain and scraper uses shackles, allowing for easy replacement of damaged parts.

Examples of conveyed materials:
Molten slag, metal, bottom ash (coal combustion ash), municipal waste incineration ash, wood chip combustion ash, etc.

Example of chain and scraper configuration:

– Remarks –

• The conveyor’s width and length can be set arbitrarily. The design will be tailored to the conveying capacity.
• When used under a boiler, the upper part of the side plates (left and right) can be opened and closed to move the conveyor.
• To improve wear resistance, basalt material and wear-resistant materials can be used for parts such as the bottom plate.
• To ease the work of chain tension adjustment, hydraulic and jack-type take-up devices are also available.
