Improvement measures for increasing production and reducing consumption of Φ3.4m×11m pre-grinding system
The Φ 3.4 m×1 1m cement pre grinding system of Hunan Liangtian Cement Co.,Ltd was completed and put into operation in 2005.Since its commissioning,the production has been low and the power consumption has been high.M32.5 cement has a low 28 d strength and an unreasonable distribution of cement particle size distribution.In order to reduce product energy consumption,improve cement quality,analyze the key factors affecting mill output and quality,a series of renovations were organized and implemented.The results showed that the system output increased from 89 t/h to 121 t/h,with an increase of 32 t/h.The annual average power consump-tion of grinding decreased from 32.29 kWh/t to 25.22 kWh/t,saving 7.07 kWh/t.
