Ball and rod mills are widely used grinding equipment in mineral processing plants. The two are similar in appearance and grinding principle, but there are differences in structure, performance, use, etc. This article will introduce their similarities and differences and tell you how to choose a ball mill and a rod mill.
Furthermore the throughput of a continuous feed mill is greater in wet grinding; probably due to the better flow properties of a pulp in comparison with a dry material. ... since the initial condition of the clay is wet and it is required in a wet form for subsequent processing. Clearly, in such a case, dry grinding, which would involve …
