Product Description. Ball mill balls are a type of ball used in ball mills, usually made of high-hardness materials such as steel, ceramics, hard alloys, etc. Ball mill steel balls is an important part of the ball mill, its main function is to carry out the grinding operation in the ball mill, and the material is crushed into the required size.

the milling process takes place during rotation as a result of the transfer of kinetic energy of the moving grinding media into the grinding product. The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product.
