اقرأ أكثرIt is lined grooved ring plate which increases the contact surface of ball and ore and strengthens the grinding. In addition, the large ore outlet increases the capacity. The particle size of grinding product is coarse, so it is applied in first grinding. Advantages of Energy Saving Ball Mill:
اقرأ أكثرA further important point of difference between wet and dry milling is that wet milling allows the easy introduction of surface active media for the reduction of the energy required to produce unit new surface or for the inhibition of aggregation of the fine particles.
اقرأ أكثرThe 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, the flow-ability needs to be increased.
