Over the past 100 years, the scholars of different countries were engaged in a great quantity of investigative works on energy consumption in the comminution process. They proposed some crushing theories such as Rittinger`s law, Kick`s law, Bond theory and others to reveal the relation of energy consumption and effect in the comminution process. The limitations in mechanism research of mineral comminution in the past and the basic features of the comminution process have been analyzed. Two kinds of catastrophe model, i.e., cusp model and swallowtail model have been put forward. The dissipative structure of the mineral comminution, entropy production rate, extra entropy, extra entropy production and system stability, has been discussed. The physical nature of the behavior that an old structure was destroyed and a new one was produced in the mineral comminution process has been brought to light.
