MODE OF FRAGMENTATION IN ROLLER BREAKING MACHINE Russian patent published in 2014 - IPC B02C4/12 

FIELD: mechanical engineering.

SUBSTANCE: roller breaking machine comprises a housing, a drive rotating roller and a fixed jaw. A surface of the rotating roller is designed with protrusions arranged parallel to the axis in the form of stops, the working surface of which is oriented to the direction of rotation. The height of the stop is larger than a half of size of a breakable piece and smaller than the gap value between the roller and the jaw.

EFFECT: method allows increasing the degree of material fragmentation in the roller breaking machine.
