Fine grinders fall under the category of impact milling equipment, a mechanical particle size reduction method used to decrease the fineness of most bulk solids. Impact mills reduce the size of large particles by introducing a striking force that stresses the natural defects, or weak spots in those particles beyond their yield strength.
