Title: CENTRIFUGAL SEPARATOR AND CENTRIFUGAL SEPARATION METHOD
Abstract:
A centrifugal separator equipped with a cylindrical basket (2) which rotates around an axis (O) and has a filtration screen (2a) provided in the body section thereof, and also equipped with an extrusion plate (7) which is housed inside the basket (2) and capable of integrally rotating with the basket, and is also capable of moving relative to the basket (2) in the axial (O) direction, wherein when discharging a cake that has been filtered by a filtration screen (2a) from a substance to be treated that was supplied to the interior of the basket (2) by extruding the cake from the opening end (2b) side of the basket (2) using the extrusion plate (7), the relative movement speed in the axial (O) direction between the extrusion plate (7) and the basket (2) is set in a manner such that the relative movement speed in the direction which causes the distance (D) in the axial (O) direction between the extrusion plate (7) and the opening end (2b) of the basket (2) to increase is slower than the relative movement speed in the direction which causes said distance (D) to decrease.
