ABSTRACT:
An apparatus for defibering conglomerates of fiber in fibrous suspensions, particularly useful with fibrous suspensions of low stock density, comprising a housing having an inlet and outlets for the fibrous suspension, a hollow cylinder within the housing, and a rotor mounted for rotation within the hollow cylinder. The annular space between the hollow cylinder and the rotor comprises a first region to dewater and screen the fibrous suspension and a second region to defiber conglomerates of fiber in the dewatered portion of the fibrous suspension. In a preferred embodiment, the annular space comprises a third region to wash dirt particles from the processed fibrous suspension and also to dilute said suspension to accommodate a further screening operation.
