Chrome cast iron grinding media in spherical ("ball") or ovoid shape, with a diameter of millimetres (½ inch) to and including millimetres (3 inches) within tolerances of 5 percent (5%), with an alloy composition of 10 percent or more (≥ 10% of total mass) chromium ("Cr") content and produced through the casting method, originating in or exported from India.
When charging a grinding mill, the standard practice is to dump tons of balls into the mill at once and replace them somewhere between once a shift and once a week. It's an inefficient practice that wastes energy, impacts product particle size distribution and risks breakage of mill linings and grinding media.
