Ten Ways to Improve the Grinding Efficiency of Your Ball Mill
To achieve the specified grinding fineness, the workload of ball mill will be increased inevitably, and then, the energy consumption and power consumption will be increased accordingly. In order to reduce the feed size of ore, the particle size of crushing product must be small, that is, “more crushing and less grinding”.
