DEVICE AND METHOD OF GRINDING SINTERS Russian patent published in 2011 - IPC B02C13/06 

FIELD: process engineering.

SUBSTANCE: invention relates to grinding sinters and the like materials that allow grinding by mechanical impacts. Proposed device comprises driven rotor with multiple blade-like grinding tools that may come in contact with material to be ground. Said tools are made up of thin knives spaced apart by equal angular distance. Note here that thickness of said knives measured in axial direction does not exceed 20 mm while identical-orientation knives repetition interval makes axially 50 mm at the greatest.

EFFECT: higher grinding effect, ruling out material sticking.
