The ball mill is a key equipment to grind the crushed materials, and the ball mill is widely used in powder-making production line including cement, silicate, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc, and the ball mill can grind various ores and other materials with dry type and wet type. But according to discharge in different ways, the ball mill can be divided into gate ball mill and overflow ball mill. The gate ball mill is enforced discharging, relatively the discharge would be coarser, but the capacity would be higher, usually the gate ball mill used for primary grinding, the overflow ball mill used for secondary grinding.
