Separation process and principle of centrifugal separator are like the following:
     rotary drum is rotate at a high speed, when the ore slurry is fed into the drum, it will also rotate speedily. Under the effect of the centrifugal force, on one hand, the heavy mineral will be deposited on the inner wall of the rotary drum and rotate with the drum; on the other hand, the light mineral will rotate at a differential drive and along the inclined direction to flow to the discharging part-thus form the tailings. After three-minute separation, the and separation part of the feeding device will automatically depart from its normal position and stop feeding ore slurry to the drum. The separation part of the discharging device will also automatically depart from its normal position after the tailings have been discharged-in order to intercept the headings. Then, the high pressure washing valve will automatically open to wash away the deposited headings on the inner wall of the rotary drum. When the headings have been completely discharged, the separation parts of the feeding device and the discharging device will automatically reset and start the next separation circulation.
