摘　　要：国内某4 500t/d水泥熟料生产线配套TRM53.41生料立磨,存在漏风严重、石灰石原料粒度大、循环风机效率偏低、挡料圈偏高等问题。通过采取改造磨辊与壳体密封、膨胀节密封,安装入磨司德伯下料器并加强料位控制,在吐渣溜子处加装无动力翻板阀等措施进行漏风治理;同时,采取调整石灰石和砂岩等物料入磨粒度,更换节能风机,缩短挡料圈高度,更换新型低阻导风环等措施进行节能改造。改造后,立磨振动减小,入磨负压由760Pa降至450Pa,系统电耗降低约2.2kW·h/t,经济效益明显。A certain 4500t/d clinker production line in China the raw mill is TRM53.41.There are problems such as air leakage,large particle size of limestone,low efficiency of circulating fan,and high dam ring in this raw mill.The energy saving modification were including upgrading the sealing between the grinding roller and the shell,as well as the sealing of the expansion joint,installing the"Stable"mill inlet feeder and strengthen material level control,and installing unpowered flap valves at the rejected material chute for air leakage control;as well as,taking measures such as adjusting the particle size of raw materials such as limestone and sands,replacing energy-saving fans,shortening the height of the dam ring,and replacing new low resistance nozzle ring for energy-saving technical reformation.After the reformation,the vibration of the vertical mill decreased,the negative pressure of the incoming mill decreased from 760Pa to 450Pa,and the raw mill system power consumption reduced by 2.2kW·h/t.It achieved significant improvement in economic benefits.
