Know-how on Improving Grinding Efficiency and Reducing

1.Feeding speed. Most ball mills can be controlled manually or automatically. No matter which way you choose, the velocity should be uniform. 2. Feeding size. The relationship between feeding size and ball mill capacity varies with mineral properties. In heterogeneous ores grinding, the finer the mineral slurry, the higher the ball mill capacity.
