Abstract
An apparatus for metering and grinding friable material has a metering screw and a beater formed of a plurality of bars which are integral with a downstream end of the metering screw. The bars are positioned parallel to the longitudinal axis of the metering screw, at apexes of a regular polygon centered on the longitudinal axis of the metering screw. A cylindrical housing surrounds the metering screw, and a cylindrical screen at least partially surrounds the beater.
