CENTRIFUGAL UNIT OF COMBINED GRINDING METHOD Russian patent published in 2017 - IPC B02C17/06 

FIELD: machine engineering.

SUBSTANCE: centrifugal unit of combined grinding method comprises a stand (1) with supporting hubs (3) in which an eccentric shaft (4) with counterweights is fastened, vertical guides (2) connected via slides (6, 7) to the frame (5) and horizontally arranged upper (8), middle (9) and lower (10) cylindrical grinding chambers with restrictive (16) and classification grids (11) and branch pipes (15). The upper grinding chamber (8) has classification grids (11). The middle and the lower ones are restrictive (16). The grids of the chambers are connected with loading transition chamber (18) at the input and with unloading transition chamber (19) at the output. The connecting branch pipes (23, 24) are rigid and arranged vertically. The lower grinding chamber (10) has a hinged flap (29) provided with an adjustable spring (30). On the upper outer surface of the middle grinding chamber (9) there are connection pipes (25) mounted for supplying liquid from a tank (27) with a dispenser (28).

EFFECT: improving the quality of the finished product by combining both dry and wet method for grinding material in one unit.
