Based on the analysis of the simplify structure and roller movement of the centrifugal miller, the author induct the four ways of the grinding of materials in roller, this is impact shattering, grinding and peeling, mangling and splitting, thereby reveals the main reasons that affect the miller grinding energy consumption are the ways of grinding, and principal main is impact grinding. On the basis of this, the formula of useful energy consumption is induced by make use of theory of kinetics, and it was proved by means of experiment. All this shows that centrifugal miller reduce energy consumption than ball miller, it provides theoretical basis for appliction of centrfugal miller. 2figs.,1tab.,5refs.
