The screw conveyor conical auger flight centres provide a continuous incremental change in swept volume of the screw. This promotes even drawdown in a full hopper situation. Combined with variable pitch the coned screw provides the best possible solution to even hopper drawdown. Standard troughs can be used with coned flights.
