Further, particle size is the most important single physical characteristic of solids. Control of particle size is an important factor because it allows better use of the material and to select more efficient particle size distribution of ground product according to their potential application. There are several research journals exclusively dealing with particle size and technology. Unfortunately, most of the research reported pertains to mineral and inorganic
materials. There are only few studies dealing with various aspects of grinding studies pertaining to food materials available in literature.
