Pulverization is the operation of reducing a solid material to powder for industrial or pharmaceutical processing or use. It is the mechanical reduction of coarse pieces into smaller particles between 100 and 50 μm in size. Pulverization or fine grinding has many advantages: homogeneous mixtures, and improvement of tolerability of preparations,

· In pulverization, the application of an external force to a particle causes it to elastically deform and then wherever the stress limit of the particle is exceeded, cracks occur at points. It is thought that the particle is destroyed by the propagation of cracks, thus completing the process of pulverization. 2. Image Credit: Thinky Corporation.

Modern boilers powder the coal to a very fine dust so that while burning, it is almost like a fluid stream. The size of the coal particles is in the range of 75 microns. This means every particle comes into contact with the air. The loss due to unburned carbon is only in the range of 0.5 % or less making the boilers very efficient.
