DISINTEGRATOR Russian patent published in 2017 - IPC B02C13/22 

FIELD: machine engineering.

SUBSTANCE: disintegrator comprises a cylindrical casing 1 with axial 3 loading and tangential 2 unloading devices. In the housing 1 to counter-rotating upper 4 and lower horizontal discs 7 rigidly attached thereto in concentric circles row of impact elements 5, 6 and 9 are arranged. Each impactor is located between the rows of impact elements of the opposing disc. The inter-row axial clearances 11, 12 and 13 in the cross-section are alternately changed along the circumference and have a maximum and minimum value every 180°. The cross section of the impactor with a minimum inter-row axial clearance is a rectangle or close to a rectangle with sides b and h, where h = 1.1…1.2b. The cross-section of the impactor at the maximum axial gap interrow a square or close to square of side b. Distances between the impact elements are reduced by grinding chamber center to the periphery of disks 4 and 7. In the second and subsequent rows of impact elements 6 and 9, the distance between adjacent impact elements in the row varies uniformly along the circumference of the circle and has a minimum and maximum value every 180°. The minimum distance between impact elements with side h = 1.1…1.2b is 10…50d_max, and the maximum distance between the impact elements with side h = b is 0.1…0.5D_max, where d_max - maximum particle size of the finished product, D_Max is the maximum particle size of the starting material.

EFFECT: higher efficiency of grinding and productivity of the finished class of grinded material.
