英文摘要：

In view of high power consumption of the 135MW ball mill pulverizing system in a certain power plant,optimization experiments and analysis are carried out.At first,the current operation conditions of the sys-tem are studied and the main factors affecting the optimal operation of the system are analyzed.After that,the optimal loading amount and the optimal diameter ratio of grinding balls,as well as optimal ventilation volume are separately determined through theoretical calculation and optimization experiments.Operation results show that the power consumption of the optimized system decreases obviously,thus the energy saving and consump-tion decrease are achieved.
