VIBRATING MILL Russian patent published in 2017 - IPC B02C19/16 B02C17/04 B02C17/14 

FIELD: machine engineering.

SUBSTANCE: mill comprises a vibrator housing provided with a resiliently mounted to the base and configured as a hollow square to form at its inner and outer perimeter of multi-start helical surfaces triangular shape and unidirectional multi-start helical lines. The chamber consists of rigidly alternately interconnected four hollow sections in the form of a hollow circular sector with four hollow rectilinear sections. Four sections are formed as the hollow circular sector. Each section is made in form of the round sector made out of strap bent alternatively to different sides along the straight bend lines, located on the strap with the same spacing and at an angle to the strap edges with the creation of the similar tetragons with two parallel sides. Subsections connected to each other free parties mentioned rectangles to form a hollow circular sector.

EFFECT: increase in grinding performance.
