Ball mills are used to obtain a product size below 150 microns. With the rotation of the mill, collision and attrition forces grind down the material in the mill chamber. The balls act as the grinding media, where contact points are created with each other and the material is either crushed or ground. The size of the feeding particles, the speed of the mill, and the size of the grinding media are just some of the factors that affect the grinding force.
The required mill size and attributes can be determined by analyzing the ore characteristics, the feed size, the desired product size, the grinding circuit type and the desired hourly capacity and output. We are happy to work together with our clients to create the optimum dimensions for the requested ball mill.
In most wet process ball mills, the mill is lined with rubber lining. Its low investment cost and easy handling for replacement make it an advantageous choice. For those clients that opt for something more resilient and durable, we recommend applying steel lining.
Our clients are in most cases provided the option to decide the lining type to be used in their ball mills. There is also the option of the client providing their own lining should they choose, where we are ready to supply the mill without lining. The lining operation can be conducted on site.
