摘要
分析了云锡公司各厂磨矿工艺现状及存在问题，在此基础上提出解决云锡公司磨矿问题的各种方案及建议。解决粗磨方案包括（１）降低棒磨机给矿粒度及减小磨矿比；（２）用周边排料棒磨机取代中心排料棒磨机；（３）用筛子取代螺旋分级机。解决细磨的方案包括：（１）改开路磨矿为闭路磨矿；（２）改格子型球磨为溢流型球磨；（３）介质尺寸精确化；（４）介质形状适宜，用短柱形介质细磨。
The grinding technolgy sircumstances and problems in some factories of Yunnan Tin Industry company are brefly analysesd,are brefly analysesd.Some plans and suggestions have been offered tosolve these problems in gringing The plans for solving coarse-grinding are:1)Reducing the feed size ofrod mill and grinding ratio.2)Replacing central discharge rod mill with peripheral discharge rodmill.3)Replacing spital classifiers with screens The plans of solving fine-grinding are: 1) chang opencircuit grinding into closed circuit gringing;2)change grate discharge ball mill into overflow ball mill;3) make mediumsize exact;4)make medium-shape suitable for fine-grinding,using short rod-shapemedium in fine-grinding.
