The apparatus also includes a cylindrical agitation unit disposed rotatably in the inner chamber and almost coaxial with the vessel. The separator comprises inner and outer annular rings and a plurality of steel studs in a mutually adjacent arrangement and extending between the inner and outer rings space, thereby defining a plurality of slits or openings therebetween for intercommunication of the inner and outer chambers. The agitation unit has a series of flutes and crowns in alternating orders on the peripheral wall thereof, and each of the flutes has a slit or through-bore intercommunicating the interior and the exterior of the unit. The vessel has an input port for feeding the material in communication with the inner chamber and an output port for discharging the crushed materials out of the outer chamber.
