DISINTEGRATOR Russian patent published in 2020 - IPC B02C13/00 

FIELD: technological processes.

SUBSTANCE: invention relates to devices for grinding soft materials. Disclosed is a disintegrator comprising a cylindrical housing with axial loading and tangential unloading devices, discs with rows of impact elements arranged in the housing with possibility of counter rotation, each of which is located between rows of impact elements of the opposite disc. In the center of the lower surface of the upper disc along the circumference, vertical posts are rigidly attached, inner ends of which are on the same diameter with the diameter of the loading device, and the accelerating cone with the generatrix located at an angle greater than the angle of the natural slope of the material is rigidly attached to the lower ends. On upper surface of accelerating cone there rigidly fixed radial blades with minimum distance between adjacent radial blades exceeding D_max, where D_max is the maximum size of the particles of the milled material, at the ends of the radial blades the beater is rigidly fixed with horizontal cutouts with height less than D_max, on upper surface of lower disc by means of vertical crosspieces of semi-circular cross section is rigidly fixed horizontal ring of semicircular cross section, on the inner surface of which at the height of the beats the replaceable horizontal baffle plates are rigidly fixed. Under each horizontal baffle plate in the lower sector of the horizontal ring there is a hole with diameter exceeding D_max, to the edge of which adjoins the corresponding vertical web with an inner radius equal to the radius of the hole, and distance between two adjacent horizontal baffle plates exceeds 2D_max, wherein external profile of beats corresponds to cross-section profile of horizontal ring and horizontal baffle with observance of process gap.

EFFECT: device provides high efficiency when grinding material.
