Energy (kW.h) consumed by each component is calculated based on the specific energy (kW.h.t −1) and mass of the component in the mixture. Figure 10 shows the content of energy consumed by anthracite as a function of grinding time. Compared with the mass content of anthracite in the mixture, a higher ratio of energy is split by it for mixtures
