Size reduction could be undergone via several methods. Compression or crushing is generally used for the size reduction of hard solids to coarse sizes. Impact produces coarse, medium, and fine sizes. Attrition or rubbing gives fine products. Lastly, cutting is done to give definite shapes. Upon undergoing size reduction process, the particles can be examined to determine its particle size
