Capacity is defined as the weight or volume per hour of a bulk material that can be safely and feasibly conveyed using a screw conveyor. Screw conveyor diameter is determined by multiple factors including capacity. The following steps are required for proper screw conveyor selection: Calculate required capacity in cubic feet per hour (ft 3 /hr).

Horsepower Calculation. Now that capacity, screw conveyor diameter, trough loading and required speed have been determined, the next task is to calculate the horse power requirements for the conveyor. Conveyor Length, which has not been considered a factor up to
Calculation of Conveyor Speed. Conveyor Speed can be most conveniently calculated, by use of the nomographs supplied on pages. To use this nomograph – first locate the two known values (screw diameter, and required capacity, in cu. ft. per hour), then with a straight edge connect these two points.
A 10-inch conveyor 35 feet long with a capacity of 10 tons per hour at 45 RPM has been selected. From the Materials Table, a Horsepower Factor of 0.8 is found for the material to be conveyed. The table also indicates Series 4 hanger bearings and shafts.
