Scraper Chain Conveyors

Scraper Chain Conveyors, which can transfer granular or aggregate product at full rate over a distance that may include a level change while protecting the transported material from the weather. Scraper chain conveyors can be used for cooling or dehydrating product during transfer (through air or water circulation), mixing and measuring, bulk handling for storage, process supplying, extracting, distributing at several points, picking up product, and lifting decanted or washed product.

Scraper chain conveyor is ideal for carrying bulk non-abrasive materials, horizontally or up a small incline, these conveyors feature a closed box.The chains scrape the floor of the box and return on guide rails at the top of the box.With a single chain, scraper flights of integral malleable steel or in the form of L attachments protrude on each side to span the box. With two strands of chain, the scraper flight is carried between strands.

Scraper chains conveyor and accessories are used in scraper conveyors for ash removal system of thermal power plants which are required to operate continuously. Due to constant abrasion of these chain links against each other as well as due to the abrasive material which is being handled in the ash removal system, surface treated chains are essential to give a reasonable service life and to work without frequent replacement.

Operation

A continuous chain with transverse scrapers moves through a closed rectangular section trough over a horizontal, sloping, vertical, or mixed route. The lower length of the chain conveys the product along the bottom of the trough.
