A sedimentation centrifuge includes a bowl (2) which is supplied with a feed mixture, i.e., a solid-liquid mixture, from a supply pipe (1). When the bowl rotates at high speed, heavy solids are displaced radially outwardly toward and sedimented on the inner wall surface of the bowl. The solid particles are then discharged through a discharge hole of the bowl and an outlet passage (5) by a screw co...

A hydraulic control system of the present invention is provided for improving a responsiveness to a speed change by compleating the speed chang with a torque pressure control hydraulic pressure after initiating the speed change with the drive hydraulic pressure. The hydraulic control system includes an oil pump for generating hydraulic pressure, a pressure regulating valve for regulating the hydra...

When liquid/solid mixtures are separated in centrifuges, in particular in worm centrifuges, with the objective of recovering the liquid phase as a valuable material, discharging the liquid via skimmers frequently leads to eddying of the liquid with the gas (normally air) present in the centrifuge, which can lead to an undesired high degree of foam formation and to an undesired reaction of the gas ...
