· Grinding is accomplished by exerting mechanical stress on a material followed by its rupture, and the energy this process requires depends upon the friability of the material. In the grinding process, the initial moisture content affects the material's mechanical properties, such as strength, stiffness, elasticity and plasticity [ 6, 26, 27, 28 ].
