The difference between screw conveyor and screw feeder
U Type Screw Conveyor . Screw Feeder Designed to measure bulk materials, the capacity or feed rate of the conveyor system can be precisely controlled using a screw feeder. The inlet of the screw feeder is always filled with water (), which is usually installed directly under the hopper, hopper or silo.
Designing Inclined Screw Conveyors for Industrial …
Screw conveyors are always control fed at the inlet by another conveyor or metering device. Rotary valves, screw feeders, belt conveyors, grinders, or even other screw conveyors typically are connected to the inlet of a screw conveyor. The flowrate or capacity of a screw conveyor is measured in cu ft/hr. If the capacity is given in lb/hr, tn/hr ...
Screw Conveyor Capacity | Engineering Guide
A 16-inch diameter screw conveyor will convey 2,496 cubic feet per hour at the maximum recommended speed of 80-rpm. The actual screw conveyor speed is calculated by dividing the Selection Capacity by the capacity at 1-rpm. 1,873/31.2 = 60-rpm. 60-rpm is the correct …
Screw Feeders | Bulk Material Transport
Kase Screw Feeders are used to meter bulk materials from hoppers or bins. Screw Feeders utilize a screw rotating in a housing to transport the material and are flood loaded in the inlet area. The bulk material moves forward with each revolution of the screw and is metered through a shroud for accuracy.

Conveyor Capacity
Calculation of Conveyor Speed. Conveyor Speed can be most conveniently calculated, by use of the nomographs supplied on pages. To use this nomograph – first locate the two known values (screw diameter, and required capacity, in cu. ft. per hour), then with a straight edge connect these two points.
Screw Feeders
The speed of the feeder screw can be determined by dividing the desired capacity in cu. ft. / hr. by the figure found in Capacity Table. For maximum efficiency, feeder screw speeds should be slower than standard screw conveyor speeds and allowances must be made for slippage of the material in the screw.
