Grinding is an age-old technique of particle size reduction to produce powders that can be used as intermediate or end products. Grinding aims to reduce the size of the particle by mechanical means such as impact, compression, shear, and cutting (Sahay and Singh, 1996).Hammer mill, plate mill, ball mill, pin mill, roller mill are commonly used grinding …
