ENGINEERING GUIDE Screw Conveyors - Manufacturer

The capacity of the Control pitch is calculated in cubic feet per hour per rpM. The speed of the screw feeder can be determined by dividing the maximum screw feeder capacity in cubic feet per hour by the capacity of the Control pitch in cubic feet per hour per rpM. Most screw feeder speeds are lower than standard screw conveyor speeds.
