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 Feeders - Screw Conveyors

Normally short in length, Screw Feeders are designed to regulate the volumetric rate of material flow from a hopper, bin or storage unit. The inlet is usually flooded with material (100% load capacity) but by incorporating changes in the construction of the flighting (diameter, pitch, etc.) and the speed of the feeder screw, the material discharge can be governed to the desired rate.
