CENTRIFUGAL PERCUSSION MILL Russian patent published in 2018 - IPC B02C7/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. Mill contains loading and unloading devices, a fixed cylindrical body, from the inner surface of which are disposed elements. Housing central section accommodates bladed rotor with self-lined pockets. In the inner volume of self-suction pockets perpendicular to the plane of the blades are located a certain step in the direction from the axis of the rotor to the periphery of the trapezoidal guide plates. Upper faces of the guide plates to the blade surface are inclined, with a decrease in the angle of inclination of the faces from the axis of the rotor to the periphery from 200 to 00°. Loading device is made in the form of coaxially installed hollow cylindrical shells. Impact elements are placed on the rotor by ring rows. Inner and outer rows are located from the center of the rotor at distances equal to the radii of the inner and outer cylindrical parts of the hollow cylindrical shells, respectively.

EFFECT: improved grinding efficiency is ensured.
