An increase in the average mill load by 1 tonne/h corresponds to a decrease in the specific consumption of the factory by 0.56 kWh/ton. It is recommended to maintain the productivity of ball mills in the first stage of grinding at the level of 35–40 tonne/h.

Compared with traditional mining ore stone ball mills, it can save 40% - 50% power consumption. Through the pressurization effect of the power distribution circuit, the start-up time is reduced by 3-5 minutes, and the production and grinding efficiency are increased by more than 20%.

To achieve the specified grinding fineness, the workload of ball mill will be increased inevitably, and then, the energy consumption and power consumption will be increased accordingly. In order to reduce the feed size of ore, the particle size of crushing product must be small, that is, "more crushing and less grinding".

Improving product quality in pharmaceutical ball milling. Ball milling is used in the pharmaceutical industry to reduce the size of particulate material such as pharmaceutical granules. Dr Alexander Krok and Dr Sandra Lenihan from Munster Technological University, Ireland, have developed a computational approach to achieve optimal, energy ...

The ball mill has been the industry's workhorse for over a century and despite its estimated meagre four per cent efficiency, little has changed over the years other than increases in the wear resistance of mill internals and the scale of the equipment. ... The main energy issue was the high power consumption of mill fans, with pressure drops ...

The specific power consumption for these two ball shapes is shown in Fig. 16. For N≤75% there is no change in the mill power draw. This occurs because the center of mass of the charge is little changed by the particle shape at these speeds. At intermediate speeds, the power draw for the non-circular balls falls off rapidly.

Under a certain speed of ball mill, the larger the filling rate, the more steel balls hit the material, grinding area is larger, grinding effect is stronger, but the power consumption is also larger.
