7.1 The High-Energy Milling Process. The fundamental principle of size reduction in mechanical attrition is the energy applied to the sample during impacts with the milling media, usually a small ball. The particles are trapped between two colliding balls and then compressed into small pieces (Fig. 7.1 ). Fig. 7.1.
