FIELD: machine building.SUBSTANCE: rotary crusher comprises housing 1, cone fixed thereto and spinning inner cone 2 with drive 3. Cones share common axle. Trapezoidal-cross-section ribs 6 are arranged in generating lines of cone working surfaces. Height of ribs 6 makes 0.1-0.5 of the clearance between surfaces of fixed and sinning cones in whatever section of crushing zone while side surfaces of ribs 6 are inclined to the base at 45-90 degrees.EFFECT: lower power input per unit product, higher efficiency.2 dwg |
