TRMK5041水泥立磨粉磨系统优化升级

Upgrading and Renovation of TRMK5041 Cement Vertical Mill Grinding System

新疆某水泥厂国产TRMK5041水泥立磨粉磨系统存在稳定性差、运行压力低、阻力分布不合理、粉磨效率低等问题。通过采取改进研磨区结构、加宽有效研磨区,增大液压系统油缸型号、增加磨辊投影压力,应用低阻风环、优化导风环结构,局部改造循环风管、减少风管弯头,应用分级粉磨技术等措施,有效提高了磨机稳定性和研磨效率,达到了增产降耗的目的。改造后,在相同水泥混合材配比和成品细度情况下,TRMK5041水泥立磨提产10%以上,粉磨系统电耗下降4.0kW·h/t,改造效果显著;项目改造周期短,施工周期仅为25d,投资回报率高。

Before modification,domestic cement vertical roller mill TRMK5041 grinding system had issues of bad stability,low operation pressure,uneven distribution for resistance and low grinding efficiency.By improving the structure of the grinding area,widening the effective grinding area,increasing the hydraulic system cylinder size,adding grinding roller projection pressure,using low-resistance louver ring and optimizing the structure,locally modifying the circulating gas duct,reducing gas duct elbows,and applying classified grinding technology,the stability and grinding efficiency of the mill were effectively improved,achieving the goal of increased productivity and reduced consumption.After the modification,under the same conditions of cement composition and product fineness,the TRMK5041 cement vertical mill increased output by more than 10%,and the system's power consumption decreased by 4.0 kW·h/t,demonstrating significant improvement.The project had a short modification period,with a construction period of only 25 days and a high return on investment.
