Grinding mills are an essential part of the beneficiation process, which aims to increase the concentration of valuable minerals in the ore. After the ore is ground, it can be further processed using various beneficiation methods, such as magnetic separation, gravity separation, and flotation.
The particle size of the ground ore is crucial for the effectiveness of these beneficiation methods. For instance, in flotation, the fine - ground ore is mixed with water and chemicals, and air bubbles are introduced. The valuable minerals attach to the air bubbles and rise to the surface, while the gangue sinks. If the ore is not ground to the right particle size, the separation efficiency of the flotation process will be reduced.

Grinding mills are one of the most energy - intensive operations in the mining and mineral processing industry. The energy required to grind ores accounts for a significant portion of the total energy consumption of a mine. Therefore, improving the energy efficiency of grinding mills is of utmost importance.
