APPARATUS FOR PULVERIZED GRINDING OF CONSTRUCTION MATERIALS

摘要

construction industry. SUBSTANCE: apparatus has cylindrical housing and cylindrical drum axially mounted for rotation within housing. Housing has cutting projections on its inner surface and mated cutting projections on outer surfaces of cylindrical drum. Mated cutting projections are arranged along helical path at an angle of 5 to alpha 45 deg. Side planar wall of charging funnel is spaced from plane of symmetry of housing and cylindrical drum, with value of space being equal to housing radius. EFFECT: increased efficiency and wider operational capabilities by allowing construction materials of different strength and density to be intensively pulverized. 2 dwg
