Comminution From Theory To Practice

Theories are proposed to explain consistently a class of phenomena and are established with experiences, hypotheses, and laws. Not all concepts need to be presented in a mathematical format. A comminution theory must incorporate fracture physics, particle breakage, stressing events in crushers and mills, material transport, comminution kinetics and models, etc. In this paper the state of knowledge of some of these aspects is discussed. An attempt has been made to show the benefit of theory in comminution practice.
