Size reduction is a process of reducing large solid unit masses into small unit masses, coarse particles or fine particles. Size reduction process is also termed as comminution or diminution or pulverization. Normally, size reduction may be achieved by two methods, namely precipitation or mechanical process. In the precipitation method, the substance is dissolved in an appropriate solvent. This method is suitable for the production of raw materials and bulk drugs. Inorganic chemicals, such as calcium carbon ate, magnesium carbonate, and yellow mercuric oxide, are prepared by precipitation method. In the mechanical process, the substance is subjected to mechanical forces using grinding equipment (ball mill, roller mill, colloid mill, etc.).
