energy consumption for grinding

  • MODELING THE SPECIFIC GRINDING ENERGY AND BALL .

    Thus, the specific grinding energy w is given now from the general expression: zIn the next Figure a comparison is made between the specific grinding energy (w) values, which are determined from Denver slide rule, and those calculated from the proposed model.

    energy consumption. Comminution is generally the single largest consumer of energy on a mine site, accounting for an average of a 53% (CEEC the future, 2012). The average grade of ores is falling in most places in the mining industry, resulting in even higher costs, due to higher energy consumption per unit of metal produc-tion.
