• Crushing into very fine particles.
• Mixing with additives to achieve desirable characteristics.

The above mentioned steps can be combined together in a single Ball Mill method. A ball mill is a cylindrical grinder used for grinding materials into extremely fine powder. The Ball mill is partially filled with the raw materials and grinding medium. The mill rotates about a horizontal axis and grinds the materials in fine particles.
