05/05/2021 Screw conveyor capacity is influenced when the pitch is lowered from standard full pitch. Lowering the auger pitch can hamper the capacity. For instance, a 1/2 pitch carries 1/2 the capacity of a full pitch screw at the same level of trough loading and speed. Selection Capacity (SC) is the capacity adjusted for special pitch, applied in the selection of the screw conveyor diameter. Calculation
