IMPACT CRUSHER FOR GRINDING LOOSE MATERIAL Russian patent published in 2022 - IPC B02C13/00 

FIELD: crushing.

SUBSTANCE: invention relates to impact crushers applicable for grinding loose material. The crusher comprises a first body defining a crushing chamber, located wherein is at least one main rotor configured to rotate around a first axis, a second body defining an inlet chamber for the material subject to crushing, in communication with the crushing chamber, located wherein is at least one secondary rotor configured to rotate around a second axis. The secondary rotor is intended for supplying the material subject to crushing into the inner part of the crushing chamber, wherein the inlet and crushing chambers are restricted by at least two side walls located substantially transversely to the first and second axes, respectively, and by at least one connecting wall placed between the corresponding side walls at least partially surrounding the corresponding rotor. The first and second axes are therein located substantially horizontally and parallel to each other. The inlet chamber is located laterally relative to the crushing chamber and said chambers are in communication by means of a connecting hole defined in the corresponding connecting walls, wherein the connecting hole is located in the lower part of the inlet chamber so that the material supplied from the secondary rotor is directed from the bottom of the inlet chamber in the direction of the crushing chamber, and the connecting wall of the inlet chamber has at least one adjustable part configured to rotate around the adjustment axis to vary the direction of intake of the material subject to crushing into the inner part of the crushing chamber.

EFFECT: crusher is characterised by high manufacturability.
