When a feeder stops, solids flow should cease. When a feeder is turned on, there should be a close correlation between its speed of operation and the rate of discharge of the bulk solid. Feeders differ from conveyors in that the latter are only capable of transporting material, not modulating the rate of flow. Dischargers are also not feeders.
