摘　　要：探讨行星效应对卧式行星磨粉磨效果及能耗的影响,通过单因素实验,分析转速比、填充率和料球比对单位产量粉磨能耗的影响,研究出各行星因子下的最节能操作参数,并进行粉磨试验。结果表明,随着行星效应的增强,粉磨熟料的单位产量能耗先减小后增大,在行星因子Z为10时能耗最低,为220.699 5 J/g;同时,随着行星效应的增强,粉体产品产量逐渐增加、粉体比表面积逐渐减小,特性粒径减小,粉体更细。The influence of planetary factor on grinding effects and energy consumption of the horizontal planetary mill was explored. Single-factor test was applied to analyze the influence of rotary velocity ratio, filling ratio as well as ratio of charge to balls on specific grinding energy consumption. The optimal energy- saving operating parameters at various planetary factors were obtained, and grinding test was conducted. The results showed： with the enhancement of planetary effects, specific grinding energy consumption of clinker first decreased and then increased, and reached the minimum of 220.6995 J/g while Z was 10; meanwhile, the throughput gradually increased, specific surface area of powder slowly reduced, characteristic particle size decreased, thus the product was finer.
