ABSTRACT:
A pulp dewatering apparatus is constructed of two press rolls arranged juxtaposed to define a nip region. At least one of the press rolls is constructed of a perforated metal outer shell surrounding a substantially rigid inner roll body. A layer of elastic material is disposed between the rigid roll body and the perforated metal shell to provide a resilient member. As a result of the elastic material, this press roll will deform during the dewatering operation to provide an extended nip region of about 3 to 5% of the overall press roll diameter.
