Drag chain conveyors have an endless chain with feed dogs (cross ribs) which runs in a closed trough. This makes them suitable for transporting bulk materials. Depending on the design of the feed dogs and trough, material can be conveyed horizontally, on an incline or vertically. Bows can be installed allowing different conveyor sections to be combined.This makes them particularly suitable for use as discharge or distribution conveyors. Material can be conveyed in the lower strand as well as the upper stand.
