Abstract

FIELD: grinding material. SUBSTANCE: grinder has hopper, screw chamber wherein a screw and cutting mechanisms are mounted, and knurled rollers arranged in the same plane, connected with the common drive and having controllable space between the rollers. The hopper is made up as a receiving funnel wherein a cone-agitator is coaxially mounted that is kinematically connected with the common drive. The depth of the grooves on each roller is equal to 1-4 mm. The diameter of the roller is 110-130 mm. The rollers, cone-agitator, and screw rotates with a speed 100-800 1/min, 40-60 1/min, and 80-100 1/min , respectively. EFFECT: enhanced efficiency. 3 cl, 1 dwg
