Large-flow dynamic anti-blocking separation system

The utility model provides a large-flow dynamic anti-blocking separation system which comprises a grinding barrel and an end cover, a screen is arranged in the grinding barrel, a protection ring is arranged outside the screen and fixedly connected to the end cover, and gaps among the protection ring, the end cover and the screen are communicated to form a rotary channel. And a certain included angle is formed between the screen holes of the screen and the axis direction. The ball mill is provided with the rotating channel, a powerful axial circulating vortex is formed by the high-speed rotation of the front-end turbine-shaped grinding rotor, the front-end turbine rotor only plays a role of radial vortex and axial vortex on the beads, and the striking effect on the beads is little due to the fact that the turbine rotor is not provided with the blades, so that almost no broken ball exists, and the ball mill is convenient to operate. The beads only pass through the surface of the screen mesh without staying unde
