CENTRIFUGAL GRINDER Russian patent published in 2010 - IPC B02C7/02 

FIELD: technological processes.

SUBSTANCE: invention is related to agricultural machine building, in particular to machines for grinding of grain and other loose materials. Centrifugal grinder includes two disks, which are coaxially arranged and installed with the possibility of rotation in opposite directions versus each other. Disks are arranged with the possibility of rotation with alternating frequency versus each other. On their internal surface there are ledges and indents arranged with wavy shape so that ledges of the left disk by their height overlap ledges of the right one and enter indents of the right one with clearance that reduces from centre of rotation to its periphery. Angle of inclination of disk side surface is more than angle of material particle motion friction, and also grooves are mounted with displacement relative to centre of rotation of the left disk to the left, right disk to the right, and their number is not equal to each other.

EFFECT: invention makes it possible to increase efficiency of grinder operation mode selection depending on quality of produced product.
