How to Make a Ball Mill: 12 Steps (with Pictures)
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.

monitoring the expected torque characteristic of the mill load during start-up. At a normal start the torque increases until the material starts sliding or cascading – usually at a mill turning angle of between 40° and 70°. This cascading leads to a torque decrease and a slow transient oscillation of torque as shown in figure 1.
