Abstract

A grinding mill containing a plurality of milling sections and composed of: a single cylindrical stator common to all milling sections; a rotor mounted in the stator for rotation about the longitudinal axis of the stator and having a plurality of milling plates spaced apart along the longitudinal axis and each disposed in a respective milling section; and a blower facility fastened to the rotor for rotation therewith and disposed near the bottom of the stator below the lowermost milling section for conveying material to be ground and conveyor gas through a central opening in the bottom of the stator to the milling sections. An auxiliary flow inducing device is connected to the outlet of the mill. The mill further includes a finger sifter mounted adjacent the outlet end of the milling sections and rotated at a rate selected independently of the rate of rotation of the rotor. Each milling plate can be formed to have an irregular working surface.
