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).

High-energy ball milling, also called mechanical alloying, can successfully produce fine, uniform dispersions of oxide particles in nickel-base super alloys that cannot be made by conventional powder metallurgy methods. High-energy ball milling is a way of modifying the conditions in which chemical reactions usually take place, either by changing the reactivity of as-milled solids or by inducing chemical reactions during milling.
