An energy split factor is defined as the ratio of energies consumed per unit mass when a mineral is ground in a mixture or an otherwise heterogeneous environment and ground alone for identical time intervals. this factor can be estimated from the initial rate of production of fines or from data for topsize feed particles remaining unbroken as a function of time, provided the trajectory of the sizthe classification of ball mill machine, ball grinding mill based on different grinding methods of adding water or not, ball mills are divided into dry type ball mill and wet type ball mill. In general, we use the wet type ball mill for the ore beneficiation. the dry type ball mill is mainly used for producing powder type materials like coal the dynamic analysis of ball mill foundation is a typical problem of soil-structure interaction, and the sub-structure method is used to estimate the structural vibration.
