STIRRING-TYPE GRINDING SEPARATOR AND GRINDING DEVICE

WIPO Patent Application WO/2017/193267

A1

A stirring-type grinding separation device comprises a separation cover (1) and a separation impeller (2) coaxial with the separation cover (1). A spiral separator (3) is disposed in the separation cover (1). One end of the spiral separator (3) is connected to the separation impeller (2), and the other end matches a through hole (10) on the separation cover (1). Under the driving of a motor, a separation rotary shaft (4) rotates at high speed, the separation impeller (2) makes materials enter a spiral groove (32) from a channel (21) between blades (22), and the mass of the materials is sequentially reduced from the bottom to the end of the spiral groove (32) under the action of centrifugal force generated by the spiral separator (3); meanwhile, the materials are pushed by the spiral groove (32) to move to a discharge channel, and when the materials are moved to a separation channel discharge opening under the action of the spiral groove (32), separation and discharge are achieved. When the separation impeller (2) rotates at high speed, separable materials can be screened out to enter the separation cover (1), so that large-particle materials and small-particle materials do not gather at a separation port at the same time, thereby improving the material discharge efficiency and speed , and achieving the technical effect of improving the grinding efficiency.
