POLYCOM high-pressure grinding roll.

of grinding. The grinding media are two counter-rotating rolls, one fixed and the other floating, between which the material is pressed. The required comminution pressure is transmitted via the floating roll. Whereas the grinding action of a tube mill involves a mixture of com-pressive and shearing forces, the POLYCOM' imposes virtually pure In centerless grinding, the workpiece is held between two grinding wheels, rotating in the same direction at different speeds.One grinding wheel is on a fixed axis and rotates so that the force applied to the workpiece is directed downward. This wheel usually performs the grinding action by having a higher linear speed than the workpiece at the point of contact.
