CENTRIFUGAL DISK SHREDDER Russian patent published in 2020 - IPC B02C13/14 

FIELD: disintegrators and crushing devices.

SUBSTANCE: invention relates to materials grinding devices. Disclosed is a centrifugal disk shredder comprising a cylindrical housing with loading and unloading pipes, opposed top and bottom disks. Lower disc has an upper conical surface with an inclination angle of the generatrix to the horizon exceeding the angle of natural slope of the material. Gap between upper conical surface of lower disc and lower conic surface of upper disc uniformly decreases from center of discs to their periphery, forming an angle between lower conical surface of upper disc and upper conical surface of lower disc, on which opposite each other there are concentric horizontal rings with uniformly and successively alternating inclined ledges, the height of each of which in each horizontal ring uniformly decreases in direction of rotation of disks. Horizontal rings of lower disc are separated by vertical concentric limiters with height equal to maximum height of inclined benches. In each vertical concentric limiter, there are through rectangular radial cutouts above upper surface of each inclined ledge.

EFFECT: the invention provides high efficiency during its operation.
