The ball mill is a tumbling mill that uses steel balls as grinding media. Ball mills can be used in wet or dry systems for bulk and continuous milling, and are most widely used in small or large-scale beneficiation plant.The feed can be dry with a water content of less than 3% to minimize the coverage of the ball, or it can be a slurry with a water content of 20-40%.

(1) The wet ball mill has better performance and higher grinding efficiency. It has low requirements for ore water content and can process ores with high water content and mud content. (2) The wet ball mill has less auxiliary equipment and simple material transportation device, so the investment is about 5%-10% lower than that of the dry ball mill.
