After entering into the high-speed turning drum, the solid-phase particles in the mixed liquid run and settle on the drum wall under the action of greatest centrifugal force; the light liquid settles at the innermost place of the drum under minimum centrifugal force. A screw feeder turns at a high speed, generating a constant speed difference, then the liquid is discharged by the liquid outlet.

The substance is fed into the accelerating cavity and enters the high-speed drum wall. Light liquid, heavy liquid, and insoluble solids settle at different layers due to specific gravities. The insoluble solid is discharged by a spiral feeder, while heavy liquid is discharged by a centripetal pump and light liquid via gravity.
