摘　　要：针对水泥粉磨系统存在的球磨机研磨体配置不合理、磨机长期低转速运行导致的主电机电耗较高等问题,对球磨机进行了节能技术改造。通过将水泥粉磨系统球磨机二仓的部分钢球研磨体更换为陶瓷球,主电机增设变频器精确控制球磨机转速,实现了球磨机工作效率的提升和能源消耗的显著降低。技改后,水泥粉磨系统球磨机主电机电流和出磨水泥温度明显下降,成品水泥质量稳定。同时,使用变频器后,球磨机台时产量增加约40t/h,磨机主电机单耗降低了约1.3kW·h/t,年节约电费约106万元,投资回收周期为1.01年。In view of the unreasonable configuration of ball mill grinding body in cement grinding system and the high power consumption of main motor caused by the long-term low speed operation of the mill,energy-saving technology transformation was carried out.By replacing part of the steel ball grinding body in the second bin of the ball mill in the cement grinding system with ceramic balls,and adding frequency converter to the main motor to precisely control the speed of the ball mill,the working efficiency of the ball mill is improved and the energy consumption is significantly reduced.After the technical reform,the current of main motor and the temperature of cement grinding are significantly reduced,and the quality of finished cement is stable.At the same time,after using the frequency converter,the output of the ball mill increased by about 40t/h,and the single consumption of the main motor of the ball mill decreased by about 1.3kW∙h/t,electricity costs was saved by about 1.06 million yuan every year,and the investment recovery cycle is 1.01 years.
