ABSTRACT:
A centrifugal separator for separating heavy metals from lighter ore includes a bowl rotatable about its axis and defining annular collection areas on the peripheral surface of the bowl at axially spaced positions along the bowl. At the peripheral wall in each area is provided a plurality of angularly spaced discharge openings which are controlled by pinch valves to periodically allow the radial escape of the collected material. The pinch valves of a first area are controlled at different timing to the pinch valves of a second area to vary the concentration of the materials collected in the different areas. The pinch valves are operated by a pressurized liquid system which is fed to the different areas through a swivel coupling mounted at a longitudinal shaft supporting the bowl.
