Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today, the largest ball mill in operation is8.53 m diameter and 13.41m long with a corresponding motor power of 22 MW (Toromocho, private communications).

The following are factors that have been investigated and applied in conventionalballmilling in order to maximize grindingefficiency: a)MillGeometry and Speed – Bond (1954) observed grindingefficiencyto be a functionof ball milldiameter, and established empirical relationships for recommended media size andmillspeed that take this factor into account. As well,millswith different ...

ABall Mill Critical Speed(actuallyball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at themillshell’s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside amillas speed varies. Use our online formula Themillspeed is typically defined as the percent of the Theoretical ...

The larger feed size, the more work that theball millneeds to do on the ore. To achieve the specified grinding fineness, the workloadof ball millwill be increased inevitably, and then, the energy consumption andpowerconsumption will be increased accordingly.

The proposed model for determining thepowerconsumption of aball millallows an assessment of theefficiencyof electric energy consumption and electricmillsidentify qualitative indicators of ...

Ball Millsare widely used in the ceramic and mining industries, where the grinding process requires strict grain size control. WEG developed an efficient solution for this application, providing a reduction in electric energy consumption of up to 35%.

The larger feed size, the more work that theball millneeds to do on the ore. To achieve the specified grinding fineness, the workloadof ball millwill be increased inevitably, and then, the energy consumption andpowerconsumption will be increased accordingly.
