  • 3 Benefits of Ball Mills 3 Benefits Of

    The ball mill can be used for both wet and dry grinding which mainly depends on the operation. The wet grinding with a ball mill includes a certain amount of water or similar liquid in order to increase the flow-ability of the materials that needs to be crushed. In the dry grinding process on the other hand the capacity is affected by the reduced flow-ability of the material. Therefore
