Get PriceEmail contactThe speed of the screw feeder can be determined by dividing the maximum screw feeder capacity in cu ft/hr by the capacity of the control pitch in cu ft/hr per RPM. Most screw feeder speeds are lower than standard screw conveyor speeds. For example, in heavy industrial applications, screw feeders typically operate at speeds less than 20 RPM. More torque is generated at lower operating speeds ...
