摘要:
针对云南某磷肥厂因钢球配比不合理、大球过多而造成的磨矿细度不高,不能很好地适应磷酸生产要求的问题,分析了入磨矿石的粒度组成.根据矿石的粒度组成采用昆明理工大学段希祥教授的精确化装补球方法,提出了一套针对该磷肥厂球磨机的精确化装球方案,同时提出了一个偏大方案和一个偏小方案,并和现厂的装球方案进行对比.针对四种装球方案进行了实验室扩大试验,研究结果表明:最佳装球方案为精确化装球方案,该方案与现厂的装球方案相比,可以使球磨机的生产能力提高14.44%;根据新方案的粒度特性曲线给出了补加钢球的方案,按此方案补加钢球可以使球磨机中的球荷组成始终保持近似于推荐的初装球组成.
Abstract:
Aiming at the problem that an unreasonable ball ratio and the low degree of grinding fineness resulted by too much big balls in a phosphate fertilizer plant of Yunnan can not meet the requirements of phosphoric acid production, the grain size composition of ore was analyzed. According to the grain size composition of ore, using the accurate costume complement method proposed by Duan Xixiang professor of Kunming University of Science and Technology, a scheme of precise ball solution for mill to the phosphate fertilizer plant, and a partial big scheme and a partial small scheme were put forward, which compared with the pack ball scheme in the factory. Experimental study results show that the accurate pack ball schemes is best, which can increase the production capacity of ball mill by 14.44%. Based on the new scheme of the grain size characteristics curve, a plan of ball load and addition is given, which can make the steel ball load composition always keep the level of recommended initial installation approximately.
