    This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. Due to the difference of its slurry discharging method, it is divided to two types grid type ball mill and overflow type ball mill.Jan 20, 2020 test. This isn’t reported in a standard ball mill work index test, but the method of Levin, 1989, can be used to calculate a “Levin B value” which is the kW h per revolution of a Bond laboratory ball mill. Dividing ball mill grindability (g of product rev) by the Levin B (kWh rev) gives the desired units of measurement (g kWh).
