Abstract
A decanter type centrifugal separator capable of discharging sludge directly from a portion of the sludge with least moisture content in a bowl so as to lower a moisture content and increase a separation efficiency, wherein a screw conveyor rotated with a difference in speed provided relative to the bowl is stored in the bowl rotated at a high speed, a dewatering cake discharge route ( ) is provided in one end wall ( ) of the bowl, an opening ( ) of the route into the bowl is provided near the inner peripheral wall of the bowl, the discharge route provides a restriction effect to the discharge of the dewatering cake, and a sedimentary layer with thick sedimentation layer is formed near the opening, whereby that portion only of the cake is discharged through the discharge route under head press of the sedimentation layer, that portion receiving the highest consolidation effect by the head press of a centrifugal force acting on the sediment, among the sedimentation layers accumulated at one end of the bowl.
