    Ball milling is a method which used to reduce size of solid materials into small particles or into powder. Thus in this practical, we used ball mill in order to crush the coarse salt into small particle sizes. Subsequently , we used sieve to separate the resulting products to determine its particle sizes and distribution of the crushed coarse salt

    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
