Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually times the shell diameter (Figure ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 2040% water by weight.

WhatsApp: +86 1820369537722 May, 2019. The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force. At a certain height, it will automatically ...

WhatsApp: +86 18203695377Adjustment to ball size could lead to significant improvement in grinding mill throughput (McIvor, 1997).The Bond's equation for ball sizing (McIvor, 1997) can help in selecting the ball size for a given ore and grinding mill simulations with ball wear modelling can also be used to identify the optimum ball size (Concha et al., 1992) for a given application.
WhatsApp: +86 18203695377Heat taken away by ventilation systems can accounts for roughly 20% of the total heat discharged by the ball mill. Improving that ventilation system brings more cool air into the inside of the ball bill, gradually reducing the internal temperature. However, the major benefit of using ball mills is the product fineness they can deliver.
