CENTRIFUGAL DEVICE FOR MIXING AND GRINDING Russian patent published in 2017 - IPC B02C17/04 B22C5/04 B01F9/10 

FIELD: machine engineering.

SUBSTANCE: invention is intended for dry and wet grinding of lump, grain and powder materials, as well as for the preparation of mixtures. The centrifugal device for mixing and grinding comprises a housing (4), a drive (5) with a shaft (2) and a rotating open container (1) with a concave bottom. The concave bottom is fixed to the housing of the fixed hood with a concave working surface. The armored sheet is fixed on the working surface. The protective ring (16) is fixed to the body or the end of the hood. Between the ring and the end of the working container, an annular slot gap (23) is formed. Three holes or channels (25, 26, 27) are provided in a housing or a cap for supplying the processed material (26), the compressed gas (25) into the annular slot gap and the discharge of the dust/gas mixture (27). The working capacity is equipped with a sealed cover (10). The cover (8) is mounted. The hood (15) is mounted on the axis inside the working container. The shoulder (22) is provided on the inner surface of the working container. The ledge forms an annular slot gap (23) with the end (21) of the cap or protective ring (16). At least three channels are arranged in the axis.

EFFECT: reduction of wear of milling bodies and working surfaces of the device.
