Nov 12, 2021The second difference between screw feeder and screw conveyor pertains to the volumetric rate of material flow. Screw conveyors can handle free-flowing material, but they cannot regulate the speed at which they discharge it. Screw feeders, on the other hand, can control the speed of the bulk material flowing through them.
