When a slurry flows into a rotor cavity (6), as the rotor units (2) rotate along with a shaft (4), the slurry is attached and extruded to the inner wall of a rotor outer cylinder (22) under the action of a centrifugal force, such that a local pressure change occurs to an overflowing hole (221), and the local pressure change diffuses around the overflowing hole (221), thereby driving the slurry to move irregularly. The slurry is dispersed by the overflowing hole (221) in the rotor outer cylinder (22) and then flows to a first overflowing channel (7), thus generating a relatively large shearing force in the first overflowing channel (7) so as to subject the slurry to secondary shearing dispersion. The slurry flows backwards from the first overflowing channel (7) along an axis, and under the action of a blocking part (31), the slurry successively flows through a second overflowing channel (8) and a third overflowing channel (9) and enters the next rotor unit (2) to be centrifugally dispersed.

In the medium grinder, when feeding by means of the feed pipe stops, the valve plate of the regulating valve is closed, thereby preventing the grinding media from flowing back into the feed pipe; and when feeding by means of the feed pipe restarts, the valve plate of the regulating valve is opened, such that the accumulated grinding media are driven by the materials to break into the grinding cavity, thereby preventing agglomerates of the materials from accumulating, and thus solving the problem of feeding being uneven.
