Grinder has semicylindrical screen provided with rectangular openings and fixed in housing. Stirring grid is positioned above housing outer surface and provided with ribs. Stirring grid receives vibrations from vibrator, with vibration amplitude exceeding opening pattern pitch along screen. Arrangement of stirring grid directly above outer surface of screen allows bulk material processing to be changed, i.e. stirring grid disintegrates supplied material and distributes it more uniformly over screen surface.
