| 中文摘要: |
| 湖南某水泥厂#1生产线采用160-140辊压机+V选+Φ4.2 m×12.5 m球磨机+高效选粉机的闭路联合粉磨系统，台时产量180 t/h，工序电耗约33 kWh/t，成品比表面积337 m2/kg。技改后出现质量波动，针对问题采用相关系数方法分析原因，提出对策，最终将系统台时产量稳定于210 t/h、工序电耗27.8 kWh/t、成品比表面积368 m2/kg，系统生产全面满足考核指标。 |
| 英文摘要: |
| The # 1 production line of a cement plant in Hunan adopts a closed circuit combined grinding system consisting of a 160-140 roller press+V-selection+ Φ 4.2 m×12.5 m ball mill and an efficient powder selection machine, with an hourly output of 180 t/h, a process power consumption of approximately 33 kWh/t, and a finished product specific surface area of 337 m2/kg. After the technical renovation, there were quality fluctuations. The correlation coefficient method was used to analyze the reasons for the problems and propose countermeasures. Finally, the system's hourly output was stabilized at 210 t/h, process power consumption was 27.8 kWh/t, and the specific surface area of the finished product was 368 m2/kg. The system's production fully met the assessment standards. |
