INERTIAL CRUSHER FOR SOLID MATERIALS Russian patent published in 2009 - IPC B02C2/02 

FIELD: mining.

SUBSTANCE: invention refers to equipment for material fine crumbling. The inertial crusher for solid materials consists of a hollow stator, of a charging and discharging devices and of the aggregate of crushing bodies. The crushing bodies are secured on a rotating rotor, installed in the cavity of the stator and equipped with a drive; the crushing bodies are made in form of freely rotating rollers, axes of which are installed to travel under effect of centrifugal forces into a position, which facilitates approaching or interacting of external surface of the roller with internal surface of the stator.

EFFECT: invention facilitates upgraded efficiency, varying dispersion of grinding; it also facilitates reducing dependence of grinding from humidity of source material.
