The breakage and liberation of minerals are the key to fluidized mining for minerals. In the ball milling process, steel balls function as not only a grinding action implementer but also energy carrier to determine the breakage behavior of ores and the production capacity of the mill. When ground products present a much coarse or much fine particle size distribution, …

Ball mill, a type of grinding mill, is a cylinder-shaped device used to grind materials like ores, chemicals, ceramic raw materials and paints. The ball mills are the key milling equipment after material has been crushed. It is divided into two rubbing ways-the dry and the wet. Ball mill is mainly composed of charging and discharging, cyclone and rotation parts.
