DEVICE FOR MIXING AND GRINDING SOLID PARTICULATE MATERIALS Russian patent published in 2017 - IPC B02C17/00 

FIELD: machine engineering.

SUBSTANCE: machine comprises loading and unloading device, grinding bodies, mounted on supports drive drum. The internal volume of the drum through the driving flaps is divided into sections. The flaps are arranged in pairs rotatably. On the surfaces of flaps are made square shaped openings. Holes are placed in concentric circles, wherein one of the diagonals of the apertures arranged radially. The drive reel is made of two coaxially placed shells.
