GRINDING MILL Russian patent published in 2009 - IPC B02C13/14 

FIELD: mining.

SUBSTANCE: invention refers to grinding equipment, mostly to fine grinding of ore and other inorganic materials, and may be used in metallurgical industry, chemical industry and other branches of industry. Grinding mill contains vertically placed cylindrical body structure with inner ring lug with holes, shaft installed in body structure in alignment with drag-cup rotor attached to it provided with hub and level section bent from centre line and located above ring lug, sieves and radial septums arranged with clearance in relation to rotor hub and provided in lower part above inclined surface of rotor with through grooves in the from of rectangles, each longer side of which is located on inclined surface of rotor, perforated cylinder mounted concentrically to body structure and forming with its surfaces and ring lug a chamber for output of ready product, vertical cylinders installed in alignment in cylindrical body structure above rotor with formation of ring chambers. In radial arises of drag-cup rotor there are vertical rectangular cutouts in which vertical cylinders are installed attached to body structure, at that upper parts of vertical cylinders are designed with holes and lower parts are blind.

EFFECT: invention allows to increase production due to generation of high values of velocity of mutual impact of particles in workspace.
