A specific energy-based size reduction model for batch grinding ball mill
It was found that the ball mill consumed 54.67 kWh/t energy to reduce the F 80 feed size of 722.2 µm to P 80 product size of 275.4 µm while stirred mill consumed 32.45 kWh/t of energy to produce the product size of 235.6 µm. It also showed that stirred mill produced finer product than the ball mill at around 40% lesser consumption of energy.

operate at higher volumetric load (60-85%v/v) than ball mills (35-45%v/v), which then leads to higher productive throughput capacity (tph/m3). Fig 2 shows that that savings for a vertical mill can range from +44% utilizing the same 25mm media size and up to 60% energy savings with finer mill pleb media (Brissette 2010).

An Improved Control Strategy for Ball Mill Grinding Circuits
An improved control strategy is proposed to control ball mill grinding circuits for energy saving and pollution reduction. A two-layer optimization architecture combined by particle size optimization layer and energy optimization layer is developed, where the optimal particle size set-point is calculated first, followed by the energy optimization step.

Grinding Media in Ball Mills for Mineral Processing
The grinding efficiency of a ball mill is determined by the product size distribution, energy consumption, and the grinding costs. According to Hassanzadeh, about 37% of the costs are used for grinding media only,13% for liners, and about 50% is used for energy in an industrial ball mill. This is evidence that media consumption has …
