ROTARY-CENTRIFUGAL UNIT OF COMBINED ACTION FOR PROCESSING OF ORGANIC AND MINERAL MATERIALS Russian patent published in 2020 - IPC B02C18/00 

FIELD: technological processes.

SUBSTANCE: invention relates to processing of organic and mineral materials in the field of production of construction materials, in chemical and pulp-and-paper industry. Proposed unit comprises sequentially interconnected cylindrical grinding chambers 1, 2 accommodating rotors 7, 8. Chambers 1, 2 are equipped with facilities for supply of initial material, additives and finished products withdrawal. In the first grinding chamber 1 there is a band set off in the loading opening direction and consists of detachable elements with classifying holes. Inside the bandage eccentrically of its central axis rotor 7 is installed, which is made of set of disk cutters 9, fixed on shaft 5. Above the loading opening of the first grinding chamber 1 there are two studded rolls 11 rotating towards each other. Loading opening size is limited by gripping angle. Inner surface of bandage in grinding zone, limited by angles of compaction-deformation of material, maximum stress, elastic expansion, is fettled by detachable elements. Detachable elements are made of angle section with classifying holes on their working surface. An arc-like plate 18 is installed in the lower part of the band limited by an angle of maximum voltage, which is hingedly fixed along the material movement in the case of the band and cantilever rests on the damping device.

EFFECT: unit is characterized by high operational reliability due to reduction of specific energy consumption on grinding process.
