Abstract (en)

[origin: WO03035267A1] Disclosed is a wet classification device in the form of a centrifuge provided with a stationary outer housing (1), a centrifugal drum (2) arranged in the outer housing, a device (13) for cleaning sediment deposited on the wall of the centrifugal drum, and inlets and outlets. The cleaning device comprises a shaft which extends into the centrifugal drum and has cutting devices (21, 22) arranged on the periphery thereof, in addition to a device for introducing a dispersing fluid in the centrifugal drum. The cutting devices are configured and arranged in such a way that turbulence can be created in the infed dispersing fluid, thereby resulting in a wash-out effect with respect to the sediment cake and facilitating the removal thereof.
