FIELD: grinding equipment used in construction industry for manufacture of crushed stone. SUBSTANCE: mill has casing with outer cone and spherical support for inner cone with shaft and unbalancing vibrator mounted for rotation on shaft. Unbalancing vibrator is hung to casing of spherical support of inner cone by means of its own self-adjusting spherical support, wherein distance from horizontal plane, where center of gravity of unbalanced part of unbalancing vibrator is positioned, to center of cone spherical support relates to distance from lower edge of milling cavity to center of spherical cone support as 1.2-1.3. Mentioned first distance relates to distance from center of spherical cone support to center of self-adjusting spherical support of unbalancing device as 1.5-1.6. EFFECT: increased yield of cubic crushed stone combined with minimal regrinding. 1 dwg
