GRINDING-MIXING UNIT Russian patent published in 2015 - IPC B02C13/14 A23N17/00 

FIELD: agriculture.

SUBSTANCE: grinding-mixing unit comprises a receiving sectional hopper (1), a dispenser (2), a crusher placed below the bottom of the dispenser (2). The dispenser (2) comprises a sectional housing (3), each section of which communicates with the sections of the receiving hopper (1) and provided with a dispensing valve (4). The crusher is connected from above with the sectional housing (3) of the dispenser by grain ducts (5), and from below - with a discharging conveyor (18) equipped with a discharge device (19). On the rotor shaft (9) of the crusher the distributing disc (10) is mounted. The number of grain ducts (5), as well as the number of loading openings (6) in the lid (7) of the crusher, the sections in the sectional hopper (1) and the sectional housing (3) of the dispenser depends on the number of components in the mixed feed formula. The loading openings (6) of the lid (7) of the crusher are placed uniformly on a circle located in the suction zone. The angle of inclination of the conical part of the crusher pallet is greater than the natural angle of repose of the combined feed.

EFFECT: ensuring the supply of continuous, simultaneous, uniform flow of all the components included in the formula, their combined grinding, uniform mixing and evacuation, eliminating the segregation of the mixture.
