ROTARY CRUSHER Russian patent published in 2015 - IPC B02C4/28 

FIELD: machine building.

SUBSTANCE: crusher casing-stator (1) is mounted on shock absorbing pads (2). A drive rotor (3), receiving (4), crushing (5) and unloading (6) chambers are installed in the casing cavity. The stationary surface of the crushing chamber and the rotor are provided with corrugated surfaces (9, 10) able of crushing the raw product (11). The casing is coupled with the loading hopper (8) stator. The loading hopper is equipped by a bucket (12) with rolling down surface (13) to move the raw product to the crushing chamber. The loading hopper provides for the adjustment of raw product feeding. The shape of the rolling down surface is determined by a guide coinciding with a flat curve line being geometrically close to the brachistochrone equation - the fastest descent line. The rolling down surface can be fitted with longitudinal corrugations to ensure the specified orientation of the raw product in respect to the crusher rotor's crushing elements.

EFFECT: invention provides for the supply of raw product for crushing with maximal speed.
