Screw Feeder - an overview | ScienceDirect Topics

An improperly designed screw feeder or belt feeder interface, or a partially opened slide gate, will often result in an eccentric flow pattern with accompanying non-uniform loads. If a sweep arm unloader is used, be aware that operating it like a windshield wiper (back-and-forth in one area) will create a preferential flow channel on one side of a silo.
