Abstract (en)

[origin: WO9009480A1] An appliance for sorting and deflaking fibre suspensions has a rotor with a horizontal axis rotatively mounted in a housing. In a first, inlet rotor zone the rotor is provided with entraining means for extracting by centrifugation contaminating particles of high relative density. The rotor is surrounded downstream by a screening cylinder and is also provided with entraining means for the fibre suspension, which deflake and sort out the fibre suspension in a second rotor zone. In a third rotor zone the fibres are washed out of the rejects after water has been added and in a fourth zone the rejects are dehydrated.
