Selection Capacity (SC) is the capacity adjusted for special pitch, applied in the selection of the screw conveyor diameter. Calculation of special screw conveyor capacities is as follows: Nomenclature: SC = Selection Capacity. CFH = required Capacity in Cubic feet per Hour (ft 3 /hr) CF = Capacity Factor. Capacity factors for Special Pitches.
Thus TSHP is calculated as follows: TSHP = 0.256 + 1.320 = 1.576 H.P. Assuming a drive efficiency of 85% resulting in a total drive horsepower of 1.853, a standard 2 horsepower motor would be selected for the drive input. The horsepower required for the above conveyor may also be determined graphically by the use of the two horsepower nomographs.

Basic Theory and Design Screw conveyors are volumetric conveying devices. With each revolution of the screw, a fixed volume of material is discharged. The purpose of a screw conveyor is to transfer product from one point to the next. Screw conveyors are always control fed at the inlet by another conveyor or metering device.
Shaftless Screw Conveyor Fill Rate Basics. Shaftless screw conveyors do not have a center shaft or hanger bearings and thus have the ability to convey more materials. Typical fill rate for a shaftless screw conveyor is 30% to 45%. Keep in mind these percentages are for average consistent flows. On dewatered sludge apps the wettest %ds and ...
