The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closed

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do.

airflow for the fluidized-bed opposed-jet mill (Figure 2b) is simpler than for a hammermill because the opposed-jet mill’s required airflow is predetermined by the size and number of its air nozzles and the air jet pressure (that is, the pressure of its compressed-air supply). For instance, if your mill has three de Laval (hourglass-shaped) air
