Ball mills are widely used in mineral processing plants for wet or dry grinding materials such as rock, ore, cement, slag, and are often ground together with classifiers.

They are made of steel and come in different sizes and shapes, depending on the application. Steel balls are very durable, have high density, and are resistant to wear and tear. They are also relatively cheap, making them a popular choice in the mining industry, where large quantities of mill balls are required. 2. Ceramic Balls.
