Abstract: An apparatus is provided for centrifuging liquid from a wet material. The apparatus includes a centrifugal drum and a stripper member positioned adjacent the centrifugal drum. The front side of the centrifugal drum is open and is arranged to be closed by a cover. The stripper is firmly connected to a driving shaft when the centrifugal drum is driven by means of a sliding clutch. A brake is provided for slowing down the centrifugal drum. During the centrifuging procedure, the centrifugal drum and the stripper rotate with the same number of revolutions and the cover is closed. After the centrifuging procedure, the centrifugal drum is slowed down with respect to the stripper and the cover is opened so that the still running stripper removes and ejects the residues.
