disc refiner

A type of REFINER consisting of one or more matched pairs of discs lined with a pattern of ribs. One disc rotates, while the other is stationary or rotates in the opposite direction. The paper stock flows from the center outward, or vice versa, and is macerated, rubbed, and cut (refined). The degree and extent of the refining depends upon several factors, including the pressure between the discs, the type of ribbing on the faces of the discs, and the consistency of the pulp suspension.
