摘　　要：以12套生料辊压机终粉磨系统的运行指标为例,分析了生料辊压机终粉磨系统现阶段运行过程中存在的石灰石及辅料进料粒度大、辊钉和辊面易磨损、循环物料和新喂物料混合不均匀、分料阀质量不一、直筒式下料口磨损严重等问题,提出了增加石灰石破碎系统、增加砂岩矿石破碎系统、合理布置密封喂料器与斗式提升机、标准化设计制作分料阀、调整除铁器位置并增加溜管、调整下料溜管角度并采用阶梯型溜管等改进优化方案。改造后,生料辊压机系统运行更加稳定,入辊物料混合均匀,辊压机产量稳定在550t/h左右,电耗稳定在10kW·h/t左右,每套生料辊压机年可节约电费约200万元,实现了节能降耗的改造效果。Based on the operation indexes of the final grinding system of 12 sets of raw roller press,it analyzed the problems in the current operation of the final grinding system of raw roller press,such as large particle size of limestone and auxiliary materials,easy wear of roller pins and roller surfaces,unevenness of circulating materials and new feeders,different quality of the parting valve,serious wear of the straight drum discharging port etc.,The improvement and optimization schemes,such as adding linestone crushing system,adding sandstone ore crushing system,rationally arranging sealing feeder and bucket elevator,standardizing design and production of parting valve,adjusting the position of iron stripper and adding chute,adjusting the Angle of chute and adopting ladder chute are put forward.After the transformation,the raw material roller press system runs more stable,the feed into the roller is mixed evenly,the output of the roller press is stable at about 550 t/h,the power consumption is stable at about 10 kW·h/t,and each set of raw material roller press can save about 2 million yuan of electricity per year,so energy saving and consumption reduction has achieved.
