MILLING DEVICE Russian patent published in 2015 - IPC B02C7/08 B02C7/16 

FIELD: engines and pumps.

SUBSTANCE: device contains the housing (1) with loading (2) and unloading (3) windows and millstones (7, 10) with surfaces with various granularity. Millstones are installed in the housing on the common axis (4). The rotation drive is designed as a flat bilateral linear asynchronous engine with the control unit. The number of couples of the engine poles is equal to two or less. Stators (12, 13) are installed with a possibility of movement along radius with reference to the engine rotor (14, 15). Rotors are designed as a disk from conducting material and rigidly fixed on millstones. Millstones and rotors are located horizontally and are movable on the axis with reference to each other. Each rotor interacts with the stator and the millstone. Stators are installed between rotors. Windings of one stator are continued from windings of another one.

EFFECT: invention simplifies design and increases productivity.
