GRINDER FOR PROTEIN FEED Russian patent published in 2018 - IPC B02C18/06 

FIELD: disintegrators and devices for crushing; machine building.

SUBSTANCE: invention relates to devices for crushing and can be used for grinding protein feeds. Grinder contains charging hopper, buffler, body, frame, electric motor, rotor with disks and knife blocks with knives in the form of flat geometric figures. Grinder has an even number of knife blocks with knives installed in parallel in checkerboard order. Surface of razor edges of the knives is made in the form of curvilinear triangle - arbelos Archimedes with sawtooth rips along the perimeter of entire surface of the cutting edges. Height of the edges is not less than the thickness of work material. Angle of slope of the rips is no more than 30°, and the rips of the knives of the subsequent knife blocks are directed in the opposite side from the knives of the previous knife blocks at the same angle. In this case, the knives are arranged to control the distance between them, depending on the size of work material.

EFFECT: grinder ensures reduction in the energy intensity of the process and an improvement in the quality of grinding of protein feed.
