Screw Conveyor Capacity | Engineering Guide
The Selection Capacity will be used to select the proper screw conveyor diameter and speed from the Capacity Table. With a recommended trough loading of 30A, the Selection Capacity must be less than the maximum capacity given in the Capacity Table. A 16-inch diameter screw conveyor will convey 2,496 cubic feet per hour at the maximum recommended speed of 80-rpm.

The initial step in engineering a Screw Conveyor is to analyze the physical characteristics of the material and the rate at which it is to be handled. 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
Screw Conveyor vs. Screw Feeder - Blog | Purvis …
Screw Feeders: Designed to meter bulk materials and are typically located at the beginning of a process. The capacity or feed rate of the conveyor system can be accurately controlled with screw feeders. The inlet of a screw feeder is always flood loaded (100-percent full) and typically it will be mounted directly under a hopper, a bin or a silo.

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 - Wikipedia
The rate of volume transfer is proportional to the rotation rate of the shaft. In industrial control applications the device is often used as a variable rate feeder by varying the rotation rate of the shaft to deliver a measured rate or quantity of material into a process. Screw conveyors can be operated with the flow of material inclined upward. When space allows, this is a very economical method of elevating …

SCREW CONVEYOR
The capacity of a Screw Conveyor should be defined in terms of cubic feet per hour. It is also important to determine 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.
