measured in a vertical plane. This decreases the area, Asc, as the cosine of the angle of conveyor slope. See Figure 4.9. However, in most cases, the actual loss of capacity is very small. Assuming a uniform feed to the conveyor, the cross-sectional area of the load on the conveyor belt is the determinant of the belt conveyor capacity. CEMA ...

CEMA has developed standard pitches for screw conveyors: full pitch, short (2/3) pitch, and half (1/2) pitch. Full pitch screws are typically used in horizontal screw conveyors because there is no loss in conveying efficiency. As a screw conveyor is inclined, a full pitch screw will lose efficiency due to the angle of the flight.

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).
