A quick glance at Rowland efficiency factors shows that operating a ball mill at conditions other than the optimum will result in an increase in the unit power consumption of the mill, and a decrease in circuit power efficiency. SAG mills, on the other hand, rarely approach the efficiency of a ball mill.

In terms of this concept, the energy efficiency of the tumbling mill is as low as 1%, or less. For example, Lowrison (1974) reported that for a ball mill, the theoretical energy for size reduction (the free energy of the new surface produced during grinding) is % of the total energy supplied to the mill setup.

One potential method is strengthening the internal and external ventilation of the grinder. Heat taken away by ventilation systems can accounts for roughly 20% of the total heat discharged by the ball mill. Improving that ventilation system brings more cool air into the inside of the ball bill, gradually reducing the internal temperature.
