A centrifugal separator includes a separation drum, a feed inlet, at least one heavy material outlet with a ring-shaped recess and at least one light material outlet. The feed inlet is located at the head of the separation drum. A feed accelerator is installed at the feed inlet. This feed accelerator cooperates with the proper form of the separation drum and the corresponding location of the material outlet to form a material differential rotation propulsion device. The material differential rotation propulsion device is capable of rotating the feed slurry material along with the separation drum in a slightly different rotation speed and forcing the processed materials to be discharged from separation drum via different outlets. The infeed flow rate is larger than or equal to the total sum of the outfeed flow rates of heavy and light materials so that the separation drum is full of materials during operation. |
