CENTRIFUGAL DISC GRINDER Russian patent published in 2023 - IPC B02C13/14 

FIELD: material grinding.

SUBSTANCE: centrifugal disc grinder is proposed, which comprises opposed rotating upper and lower discs. On the upper surface of the lower horizontal disk from the centre to the periphery, a paddle spreader and concentric vertical rings with radial rectangular holes made symmetrically about the vertical axis are fixed. Radial ribs of rectangular cross section are fixed between concentric vertical rings along the radius. The working surface of each radial rib is in the same plane with the rear side wall of the radial rectangular hole in the direction of rotation of the lower horizontal disk. On the lower surface of the upper conical disk, radial ribs of rectangular cross section are fixed to provide a manufacturing clearance between the ends of the radial ribs of the lower horizontal and upper conical disks.

EFFECT: efficient grinding of materials.
