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 Conveyor Engineering Guide - Horsepower …
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. Hard iron bearings and hardened coupling shafts have been selected to suit this requirement.
Screw Conveyor Corporation
The capacity of a Screw Conveyor should be defined in terms of cubic feet per hour. It is also important to deter-mine the maximum capacity the conveyor will be required to handle. This capacity is very often stated in terms of tons or pounds per hour. However, the material to be handled often varies in density. Therefore, the maximum volume or capacity in cubic feet per hour is the maximum ...
