摘要

INTERCHANGEABLE VOLUMETRIC SCREW FEEDER A volumetric screw feeder is interchangeably convertable from a twin screw feeder to a single screw feeder without modification of the gearing or drive means. The change from twin screw feeder to single screw feeder is made by interchanging the screws and the feeder hopper. Moreover, the drive shafts for all of the screws are brought out through a unitary seal.
