Material returning to the mill is called circulating load, and the ratio of this material to new feed may vary from a few percent to 600 percent or more.

Jul 03, 2021· Principles of Grinding. In all forms of grinding, three different interactions occur between the abrasive and the machined material. Cutting occurs where the abrasive grain is sufficiently exposed to penetrate the workpiece material and curl a chip, and sufficient clearance exists between the grain, bond and workpiece to flush the chip with coolant or throw it away by wheel action.
