Aug 10, 2020 Ball mills are a special instrument used to break up hard solids into a fine powder. They are similar to rock tumblers in that the instrument is a rotating container filled with heavy balls to grind the substance into powder. Ceramic material, crystalline compounds, and even some metals can be ground up using a ball mill

Nov 21, 2017 However, what can cause the liner wearing of ball mill? Firstly, wrong installation method can lead to uneven liner stress, then lead to liner fracture. Secondly, in the process of ball mill manufacturing, the selected lining uses poor material quality, the service life is much is shorter, and the wear resistance is poor, so liner is easier to cause wear problem

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones
