Drag Chain Conveyors consists of two endless chains with spaced paddles spared evenly between them which drag along the bottom to transport the material to the required destination. The surface area and the speed of the chain movement determine the amount of material to be moved by each paddle.
The good thing about Drag Chain Conveyors is the speed of the chains is relatively moderate so the energy consumption done is minimised and in turn, the complete set of the conveyor becomes simple to use and also cost effective. The chains can be replaced once wear down occurs.
Drag Chain Conveyors is preferable to industries using dry materials, non-abrasive non-sanitary products like grains, cement manufacturers. The main disadvantage with this is the wear down effect, the chains have to get replaced more oftenly.
