MILLING-AND-CRUSHING MACHINE Russian patent published in 2009 - IPC B65G65/28 B02C18/28 

FIELD: machine building.

SUBSTANCE: invention is related to equipment for loosening of bulked materials and may be used for crushing of large pieces of material on above-bunker grates. Milling-and-crushing machine includes automotive trolley (1), in body of which actuator is installed with cutters (2), which is made of two identical cylindrical rotors (3, 4) that are coaxially installed on their bearing supports (7, 8) and may rotate independently from each other. Cutters on rotors are installed along helical lines in opposite directions from the middle of every rotor. Bearing supports of cylindrical rotors installed in point of rotor end sides adjacency are covered with jacket in the form of cylinder with diametre equal to rotors diametre.

EFFECT: invention excludes effect of one drive at the other one, reduces energy intensity of unloaded material damage, reduces metal intensity and increases machine stability.
