CENTRIFUGAL DISC GRINDER Russian patent published in 2023 - IPC B02C7/00 B02C13/20 

FIELD: material grinding

SUBSTANCE: devices for grinding various materials, used in the production of construction materials, as well as in other industries. The centrifugal disc grinder contains a cylindrical body 1 with loading 2 and unloading 3 branch pipes, oppositely rotating upper 4 and lower 5 discs. U-shaped bumpers 7 are rigidly attached to the lower end of the loading pipe 2 along the perimeter, to the outer vertical walls of which the upper horizontal disk 4 is rigidly attached, and the lower horizontal walls are in the same plane with the lower surface of the upper horizontal disk 4. A distribution cone is rigidly attached to the central protrusion of the lower horizontal disk 5, in the lower part of which a horizontal ring with vertical blades is rigidly fixed, on the outer ends of which prismatic hammers symmetrically located relative to the axis of rotation are rigidly fixed, located in U-shaped bumpers with a process gap between the outer profile of prismatic hammers and the profile of the inner surface of U-shaped bumpers. On the lower surface of the upper horizontal disk and on the upper surface of the lower horizontal disk, radial ribs are rigidly fixed with a vertical process gap between them. The minimum distance between adjacent prismatic hammers and adjacent U-shaped bumpers exceeds 2D_max, where D_max is the maximum particle size of the crushed material. The vertical dimension of the prismatic hammers is D_max. The vertical gap between the working surfaces of horizontal discs is (0.5...1.0)D_max.

EFFECT: improving the efficiency of the grinding process.
