In order to reduce the temperature in the mill and improve the grinding efficiency, a small amount of mist water can be sprayed into the grinding bin to lower the temperature in the mill to below 50°C.

The amount of grinding aid is unreasonable. Under the premise of not harming the performance of the product, a small amount of grinding aid can be added, which can not only accelerate the crack propagation in the crushing of materials, reduce the mutual bonding between fine powders, and effectively improve the performance of the powder.

Grinding efficiency, but also improve the energy-saving efficiency of the bentonite milling machine. However, grinding aids for bentonite milling machines should be added in accordance with the national standards. In general cement production process, the amount of grinding aids added should not exceed 1%. The proportion of grinding aids for other materials can be inquired through the national standards.
