    Dec 26, 2004 In that case simply disregard its mathmatical removal. Multiply this area by the pitch distance and you have determined the 100 volume displacement per revolution of your screw conveyor. You obviously may or may not want to consider 100 volume. Finally, if it is an existing unit determine the RPM. If it is a new design then you can select the RPM.

  • Sizing a Screw Conveyor

    Sizing a Screw Conveyor

    The first step in sizing a screw conveyor is to determine the diameter. The diameter is a function of the rate of the conveyed material, its density, trough fill level, screw pitch and speed of the screw. To ease the calculation, most screw conveyors are full pitch, meaning the distance from flight to flight is the same as the diameter, and are ...
