ABSTRACT:
An improved pressurized disc refiner having a pair of oppositely facing non rotating refiner plates and a rotating disc having refiner plates on each face thereof juxtaposed the non rotating refiner plates. The rotating refiner plates and at least one of the non rotating refiner plates are axially adjustable to compensate for wear and to insure that an equal and opposite thrust force is produced on opposite sides of the rotating refiner plates. During the plate changing operation, both of the non rotating refiner plates are independently movable axially along the drive shaft away from the rotating disc for simultaneous access to both of the non rotating refiner plates and both of the rotating refiner plates to facilitate changing of the refiner plates. The refiner has a split mechanical stop to limit movement of the axially adjustable non rotating refiner plates axially away from the rotating refiner plate during the refining operation of the apparatus. The refiner also has one or two horizontal inlets located on the side of the refiner.
