A flocculating, grading, and dewatering device includes a tank body, a mixing zone, a flocculent settling zone, a centrifugal dewatering zone, and a particle screening zone. An initial material is mixed with a chemical agent for a flocculation reaction, a lower sediment material settles and an upper liquid overflows. In the centrifugal dewatering zone, a screen basket is allowed to rotate to facilitate a centrifugal movement of the sediment material, water in the sediment material moves into a guide cavity and then flows to a centrifugate outlet, and then a dewatered material in the screen basket is removed out of the screen basket. In the particle screening zone, a screening mechanism screens particles of different size grades in the dewatered material, and water generated flows downward and is discharged; liquids discharged from the centrifugate outlet and the overflow port are combined, and then discharged through a mixed liquid outlet.

A seal for a centrifuge for preventing material from leaking out of an effluent portion into a drive portion where the seal is disposed between a basket carrier and a drive portion, and the basket carrier is disposed between the effluent portion and the drive portion. The seal can also be disposed on a stiffener, the stiffener disposed between the basket carrier and the drive portion. A sealing arrangement for a centrifuge including a contact seal and a labyrinth disc, for preventing liquid from leaking out of an effluent portion into a product discharge outlet and for preventing material from entering into the effluent portion through the product discharge outlet. Also provided is a centrifuge incorporating the seal and/or the sealing arrangement.

A centrifuge for separating minerals by specific gravity is disclosed. The centrifuge rotates to circulate slurry across a collection region and to subject slurry in the collection region to centripetal forces that facilitate stratification within the collection region by the specific gravity of the constituent minerals of the slurry. Energy, such as acoustic energy, is coupled with the collection region and enhances the stratification by specific gravity within the collection region.
