DISINTEGRATOR Russian patent published in 2013 - IPC B02C13/22 

FIELD: process engineering.

SUBSTANCE: invention relates to grinding of low-abrasive materials to be used in production of construction materials. Disintegrator comprises rotors, loader and drives. All rotors are arranged symmetrically in scroll case in one plane to allow rotation of impact element outer rows toward unloader. Scroll case has rectilinear wall while unloader is equidistant from rotational axes of rotors and located opposite said rectilinear wall. Two loaders abut on said case to feed materials to be ground to centres of rotors rotation.

EFFECT: higher efficiency of grinding.
