a ball mill uses impact

What is a Ball Mill?

Ball mill uses steel ball as grinding medium. Because the steel ball is in point contact with the ore, the grinding products are of high fineness, and the particle size of the products is relatively fine, which is prone to over grinding, so ball mill is not suitable for the re-selection production line in ore dressing.
