under the combined action of centrifugal force and washing water, the ore particles with high specific gravity are deposited on the inner wall of the inner rotary drum 11 to form roughing concentrate, and the ore particles with low specific gravity are discharged along with ore flow from the round edge of the big end and fed into the small end of the outer rotary drum 12 for scavenging;
after the ore particles enter the groove cavity 14, under the action of centrifugal force, water stains on the ore particles are discharged through the blocking net 8, so that the resistance driven by water on the surface of the ore particles is reduced, and the influence on the scavenging effect is avoided;
the rotating shaft 3 reversely rotates relative to the rotary drum 2, so that the rotating speed of the fan blades 72 relative to the rotary drum 2 is increased, further air-drying treatment is carried out on ore particles in the rotary drum 2 by the fan blades 72, the resistance driven by water on the surface of the ore particles is reduced, the ore dressing precision during scavenging is increased, and the influence on the scavenging effect is avoided; the ore particles with high specific gravity are deposited on the inner wall of the outer rotary drum 12 to become scavenging concentrate, and the ore particles with low specific gravity are discharged from the big end along with the ore pulp flow to become tailings;
in the driving mechanism 4, a motor 41 is started, the motor 41 drives a driving wheel 42 to rotate, the driving wheel 42 drives a rotary drum 2 to rotate through meshing with a driven wheel 43, meanwhile, the motor 41 drives a rotary shaft 3 to reversely rotate relative to the rotary drum 2 through a belt transmission pair 44, and the rotation speed of the rotary drum 2 and the rotary shaft 3 can be changed through matching of the driving wheel 42 and the driven wheel 43, so that the screening range of ore particles during scavenging is changed, and the problem that the screening effect of scavenging concentrate is poor when the scavenging concentrate is subjected to larger centrifugal force is avoided;
after the tailings are screened, the rotating speed of the motor 41 is gradually increased, and scavenging and roughing concentrate is discharged.
