Ball milling is a type of grinder used to grind materials into fine powder. Ball mills rotate around a horizontal axis, partially filled with the coarse salt to be ground plus the grinding medium. There are many types of grinding media suitable for use in a ball mill, each material having its own specific properties and advantages.
8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
