Screw Conveyor Capacity Engineering Guide

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).

Screw Feeder Design for Metering Bulk Materials ...

The speed of the screw feeder can be determined by dividing the maximum screw feeder capacity in cu ft/hr by the capacity of the control pitch in cu ft/hr per RPM. Most screw feeder speeds are lower than standard screw conveyor speeds. For example, in heavy industrial applications, screw feeders typically operate at speeds less than 20 RPM. More torque is generated at lower operating speeds ...

DESIGN AND SIZING OF SCREW FEEDERS

Calculation of the nominal flow can be done once the screw geometry, its rotation speed and the filling coefficient are known. The flow rate of a screw conveyor or feeder depends on a number of interlinked factors: - geometry of the screw - rotation speed - inclination - geometry of the feed hopper and tube - flowability of the material. The risk of backflow increases with the inclination and ...
