1. Mineral Processing: Ball mills are widely used in mineral processing industries for the grinding and separation of ores. They are essential in the preparation of ore for concentration and extraction processes. 2. Ceramics: Ball mills are used in the ceramics industry for the fine grinding of clays, glazes, and other ceramic materials.
