Ball mill is the key equipment for grinding crushed materials, which can be used for grinding limestone, dolomite, calcite and other ores. Its crushing ratio can range from 3 to 100, and both wet and dry grinding can be used as its abrasive methods. In addition, ball mills can grind materials into very fine particle sizes and can be quickly completed, making them …

The horizontal design makes it easy to operate and maintain, and it is suitable for both wet and dry grinding. 2. Vertical Ball Mill. A vertical ball mill is a type of ball mill where the barrel is vertical instead of horizontal. It is designed for fine grinding of materials, and it is usually used in laboratory or small-scale production.
