Screw Conveyor Corporation

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.

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.
