Design. Ball mills consist of a container, usually cylindrical, filled with grinding balls, which is connected to an electric motor, which spins the container. The container is made of metal or plastic. The grinding media (balls) are often made of lead-antimony alloy, or tungsten carbide. Steel is usually avoided, since it will spark.Web

balls reduced the number of particles coarser than 1 mm by about 5%. In case the feed to ball mill was equal to 1200 Mg/h, it resulted in a reduction of 60 Mg/h of the weight of coarse particles in circulation. It also enabled the processing of a larger feed size without the risk of balls being thrown from the mill. No negative impact on the ...Web
