The style of chain and flight for the drag conveyor is determined by what material the drag is moving and whether there will be a change in elevation. Drag conveyors can also be part of a quench or settling tank. The drag in applications like this will slowly drag material across the bottom of the tank, up one side and out of the tank.

One of the benefits of drag conveyors is that they can handle an extreme range in material particle size, from ash finds to large clinkers. They can also be designed to handle very abrasive material.
