Mg). The grinding rate was higher for the thin hammer configuration [8,9] reported that the specific grinding energy of uncrushed kernels ranged from 72.3 to 146.7 kJ·kg −1 and from 67.0 to 114.4 kJ·kgfor Turnia and Slade, respectively. The crushing caused a decrease of specific grinding energy in both cultivars. The total specific grinding
Grinding Wheel: Cutting Wheel: The grinding wheel has good strength which avoids cutting improper shape and size. The normal cutting tool doesn't have abrasive. So it will not provide better finishing accuracy as grinding wheel provides. The chances of wear and tear are high in cutting wheel : A grinding wheel having low chances of wear and tear.
