A specific energy-based ball mill model: From batch .
2016/02/01· For continuous ball mill operation, the mass flow rate of mill product, P i, is the result of mill ground product, H i and discharge rate, D i, expressed by Eq. (6) : (6) P i = H i · D i The product size distribution can be calculated as a ratio of the mass flow rate by size ( P i ) to the total mass flow rate.
