Symptoms of poor liner design, which means your mill liner may require re-evaluation, include a noisy mill and broken mill liners. A noisy mill produces a distinct impact rattling, which indicates that the grinding media is impacting directly on the liner instead of on the toe of the grinding charge.

The ball mill can be operated in a wet or dry way, depending on the material properties and the intended use. The wet ball mill is usually preferred when the material to be ground is wet, such as in the case of ore processing. On the other hand, the dry ball mill is suitable for grinding dry materials, such as cement, limestone, and coal.
