Abstract
A centrifugal separator for the concentration of suspended solids has a rotatable drum and hydraulically operated outlet valves uniformly distributed about the periphery of the drum in the plane of greatest drum diameter. The valves include nozzle apertures and movable valve bodies therein. The valve bodies are mounted to close the nozzle apertures by the centrifugal force of the drum at full rotary speed and are displaced to an open position in response to the feeding of operating liquid during use. A liquid ring valve controllably releases the operating liquid to effect the reclosing of the nozzle apertures under the action of the centrifugal force.
