对溢流型球磨机工作过程中出现给料过多的情况进行原因分析，针对这些原因给出可能解决问题的方案，再根据实际情况分析方案的合理性，并在实际设计和现场调试过程中采用相应的方案，使溢流型球磨机与物料输送系统之间建立联锁关系，实现必要的联锁控制，给出联锁控制的流程图和PLC程序梯形图。最后给出了现场实际应用的效果。%As a crushing equipment , ball mill has been widely applied in the mining and chemical industries . Overflow ball mill is one of the equipments w hich have been used earlier and commonly . During the practi-cal application in the mines , due to over feeding , the ball mills are overloaded , broken and even broken dow n . T he thesis has analyzed the reasons of over feeding , and brought up the solutions accordingly . Then , based on the actual situation on site , the most reasonable and effective solution will be selected . During the designing and commissioning , the solution will be applied and established interlocking relation-ships between the overflow ball mill and the material transfer system . Control flow diagram and PLC pro-gram diagram will be provided as well .
