Types of Screw Feeders | Engineering Guide

With the screw feeder inlet flood loaded (100-percent), the design of the screw in the inlet area and the screw speed determine the desired capacity or feed rate. Most screw feeders are less than 20-feet in length because the use of internal hanger bearings is not recommended. In most applications a short screw feeder will meter a bulk material ...


Case Study

Coal was transferred from outdoor stockpiles to a pulverizing roller mill via a belt conveyor and a triple-gate dump valve located at the mill inlet. When air leaked into the mill, the pulverized coal was not conveyed away efficiently. Consequently, poor flowing coal accumulated in the mill and clogged the unit requiring costly downtime.
