DEVICE TO MIX AND GRIND BULK MATERIALS Russian patent published in 2014 - IPC B01F7/00 

FIELD: machine building.

SUBSTANCE: device to mix and grind bulk materials contains frame, loading/unloading device, horizontal drive drum, the drum has on the internal surface the helical guides, shaft installed in the drum parallel to its axis, the radial elastic elements are secured to the shaft. The new feature is that the helical guides on the internal surfaces are made from separate alternating in axial direction areas, the grind discs are secured on the shaft in zone between areas, the discs have on surface the helical grooves, at that diameter of the grind discs increases in direction from the materials loading device to the materials unloading device, and in area of the helical guides the radial elastic elements are installed alternating with the grind discs.

EFFECT: higher efficiency of grinding process.
