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

FIELD: disintegrators and crushing devices.

SUBSTANCE: invention relates to devices for grinding material. Disclosed is a centrifugal disk shredder comprising a cylindrical housing with loading and unloading pipes, opposed top and bottom disks. Upper surface of lower disk and lower surface of upper disc are tapered with angle of inclination of generatrix α>ϕ, where ϕ is angle of natural slope of material. On the upper surface of the lower disc and on the lower surface of the upper disc there are concentric ledges and grooves of a semicircular cross-section, the size of which decreases from the center of the disks to their periphery from 2D_max to (0.1…0.5)D_max, where D_max is the maximum size particles of ground material. Ledges of upper disc with process clearance enter into grooves of lower disk, protrusions of lower disc have tangential rectangular cutouts along entire length of circle in direction of rotation of upper disk, height and width of each cut coincides with depth and width of corresponding groove.

EFFECT: invention is aimed at improvement of grinding process efficiency.
