When ball mill works, the grinding media and the materials of the cylinder are rotated to a certain height. Due to the gravity, they fall down from the tube wall. The materials are crushed by impact action of the grinding media, and friction and shearing action of grinding media's rolling and sliding.
Alloy forging and hot rolling wear-resistant steel ball is produced by automatic production method. The whole round steel is heated by medium frequency electric furnace, rolled into ball by counter roll, then quenched and tempered, and 60-100 balls are produced per minute. It is suitable for wet grinding ball mill and semi autogenous mill.
