Bond Work Index (Energy equation)
Power as kW = E * (t/h dry solids) A ball mill can safely operate at 90% of its motor rated power, so choose a motor size like this: Motor size as kW = Power / 0.90. You will not get a circulating load prediction from a Bond calculation. The assumption is that your secondary circuit is "efficient", whatever that might mean.
