reference surface. The workpiece is free to shift, and if the support surface is the one being ground, the axis of rotation also shifts. centertype grinding Grinding by rotating the workpiece around a fixed centerline established by the chuck or centers in which it is held. compensator The device that advances (crossfeeds) the grinding
The high unit capacity SAG mill/ball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs, which has in turn made many lowgrade, hightonnage operations such as copper and gold ores feasible. Future circuits may see increasing use of high pressure grinding rolls (Rosas et al., 2012).
Mill Speed . No matter how large or small a mill, ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar rolling mill, its rotational speed is important to proper and efficient mill operation. Too low a speed and little energy is imparted on the product.
