Spherical grinding media are predominantly used in final stages of ore grinding. The spherical balls change shape through breakage and wear. Though this is universal in milling, its contribution and effect on millingics, load behaviour and mill power is not fully established. One area that is usually ignored is the relationship between media shape and mill power. The objective of this
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. Its an inefficient practice that wastes energy, impacts product particle size distribution and risks breakage of mill linings and grinding media. Fortunately, we can offer you a better option with our Mill Grinding Ball Charging
Mill Linings: Ball and Pebble Mills may be lined with rubber, ceramic and wear resistant metallic liners. Grinding Media: Mills may be charged with ceramic, steel and alloy steel grinding media. These are spherical or cylindrical in shape and range from 6 mm to 100 mm in size.
