Wet ball mills are widely used in mining, building materials, chemical, and other industries, and their grinding efficiency directly impacts production costs and product quality. To improve the grinding efficiency of wet ball mills, a comprehensive optimization of equipment structure, process parameters, and operation management is necessary.

First, the rational selection of grinding media is crucial. The size, material, and proportion of steel balls directly affect the grinding effect. A combination of large and small balls is usually employed, with large balls for coarse crushing and small balls for fine grinding, which can improve overall crushing efficiency. Regular inspection of steel ball wear and timely replenishment or replacement are also necessary to maintain the optimal filling rate.

Secondly, controlling the appropriate slurry concentration and feed particle size is important. Excessively concentrated slurry increases viscous resistance and reduces grinding efficiency; excessively dilute slurry reduces effective collisions. A solid content of 60% to 70% is generally considered optimal. The feed particle size should also be as uniform as possible and meet the equipment requirements, avoiding excessively large particles that increase the load and excessively small particles that result in ineffective grinding.

Thirdly, optimizing equipment operating parameters is essential. The rotation speed should be approximately 75% to 85% of the critical speed to ensure that the steel balls obtain sufficient falling height without centrifugal operation; continuous and stable feeding should also be ensured to avoid empty grinding or overloading.

Finally, strengthening equipment maintenance is crucial. Regularly cleaning the scale buildup on the inner wall of the cylinder, checking liner wear, and maintaining good lubrication of the transmission system can reduce energy consumption, extend service life, and indirectly improve efficiency.
