A ball mill is also commonly employed for fine grinding. In a ball mill, grinding energy is transferred to materials through media such as balls, rods, pebbles, by moving the mill body . For both types of mills the mechanisms by which particle size is reduced follow the same principles.
Details
Since the particle size, shape, specific surface area, and purity of the ground calcium carbonate (GCC) decide its usability in the paper, paint, and plastic industries, the effect of grinding is important. However, the effect of stirred and ball mill grinding on the particle shape of GCC by dynamic image analysis (DIA) is still lacking in the literature.
