CENTRIFUGAL DISC GRINDER Russian patent published in 2021 - IPC B02C13/14 

FIELD: material grinding.

SUBSTANCE: invention relates to a device for grinding material. The centrifugal disc grinder contains housing and oppositely rotating upper and lower discs. Concentric rings with consistently and evenly spaced radial through slots along the circumference of each concentric ring and along its height, as well as a spreader with radial blades, are rigidly fixed on the upper surface of the lower disc. On the lower surface of the upper disc, vertical annular protrusions are rigidly fixed, along the length of the inner and outer side surfaces, of which semicircular protrusions are sequentially and evenly located, located between the concentric rings of the lower disc. The radial clearance between concentric rings and vertical annular protrusions, as well as between concentric rings and semicircular protrusions, decreases uniformly from the center to the periphery of the horizontal discs.

EFFECT: increasing efficiency of the grinding process.
