1) Grinding wheel speed and workpiece speed. 2) Grinding wheel sizes and workpiece sizes. 3) Infeed amount. The above relations are explained by the following figure. D: Diameter of grinding wheel (mm) d: Diameter of workpiece (mm) V: Wheel speed (m/min) v: Workpiece, wheel speed (m/min) f: Feedrate.

Roller mills are also more sensitive to instantaneous changes in the feed rate than are other pieces of process equipment. Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill "sees" instantaneously unless some damping system such as a surge hopper is used.

developments in grinding technology as applied to tire and roller resurfacing. We gave several seminars and published articles related to tire and roller grinding. As part of our grinding service we measure the shell ovalities and make roller adjustments to correct kiln misalignment caused by the changes in the tire and roller radiuses.
