金川二选厂磨浮车间全部5个系统的浮选作业区都装有 XJC-80充气机械搅拌式浮选机（该型号浮选机占到全车间浮选机总台数的50％左右）。在过去相当长的一段时期内,该型号浮选机的槽体衬板所采用的材质为ZGMn13。但是在使用过程中,ZGMn13为材质的槽体衬板所出现的问题日益突出, 1 存在的问题 1.1 使用寿命较短 备件消耗费用过高 从使用情况来看,ZGMn13为材质的槽体衬板的平均使用寿命仅为24个月左右,而衬板的价格为4000元/块（由厂机动科 Jinchuan II mill flotation plant all five systems flotation operating area are equipped with XJC-80 inflatable mechanical mixing flotation machine (the model flotation machine flotation machine accounted for the entire workshop about the total number of 50%). In the past a long period of time, this model flotation tank liner material used by the ZGMn13. However, the use of ZGMn13 material for the tank liner problems have become increasingly prominent, 1 existing problems 1.1 Short life Spare parts consumption costs are too high From the use of view, ZGMn13 material for the tank liner The average life expectancy is only about 24 months, while the price of the liner is 4,000 yuan / block
