Size reduction is a process of reduction of material to smaller pieces to coarse particles or to powder/fine powder. Size reduction process is also known as Comminution and Grinding. When the particle size of solids is reduced by mechanical means it is known as Milling. The size reduction operation can be divided into two major categories depending on whether
