Zusammenfassung:A high speed ground wood disc refiner having a pair of oppositely facing fixed refiner plates and twin rotating discs each carrying refining plates juxtaposed the fixed plates. The rotating discs are axially adjusted on the drive shaft by a parallel piston-cylinder hydraulic system which insures that an equal and opposite thrust force is produced by each rotating head. Since the thrust forces are absorbed by the drive shaft, this arrangement permits the use of very light bearings on the drive shaft, resulting in economies of manufacture and maintenance.
