Trough Chain Conveyor, Drag Chain Conveyors, En-masse .

Trough Chain Conveyor, Drag Chain Conveyors, En-masse .

The trough/drag chain conveyor is a conveying device that continuously conveys powder, granules, small pieces, and other loose materials in a closed casing by means of a moving scraper chain. Because the scraper chain is embedded in the material being conveyed, it is called the trough/dray chain conveyor.
