Abstract: A magnetic separator includes a channel, having a plurality of walls, one of which includes a vertically traveling conveyor belt; a magnetic coil is arranged on one channel wall for producing a high intensity magnetic field; inlet means is provided for introducing a carrier medium into the channel and an injecting means on a side channel wall opposite the magnetic coil and downstream of the inlet charges material into the medium. A doctoring member removes magnetic particles drawn to the conveyor belt and means spaced from said one wall removes non-magnetic particles and carrier medium.

Abstract: In a method of degasification of viscose liquids by means of centrifugation the liquid is brought onto the interior wall of a rotor in the form of a flowing film and divided into a bubble-poor and a bubble-rich portion, the bubble-poor portion being separated from the bubble-rich portion prior to leaving the rotor and withdrawn from the rotor wall by means of at least one pump. In a preferred form of the invention the bubble-rich portion of the liquid is also withdrawn separately from the centrifuge by means of at least one pump and returned for renewed centrifugation. The invention includes a centrifuge for carrying out the method.
