Calculating screw conveyor flowrate
· Please assist with a formula for calculating flow rate. There are charts available, but we need to know the loading that you desire, the size of the screw conveyor, the pitch of the screw conveyor. Then the charts will give capacity of cubic feet per hour per rpm. You can then use this up to a "maximum economical speed".
