Application of correlation analysis in the debugging of cement grinding system
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 4.2m×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 pro-pose 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.
