| 中文摘要: |
| 我公司水泥粉磨采用Φ1 500 mm×1 000 mm 辊压机+Ф3.8 m×13 m 圈流球磨联合粉磨系统，2011年投运后，运行状况一直较差，产量不达标，同时水泥工序电耗高。本文介绍了该水泥磨系统的节能技术改造，包括将双闭路生产系统改造成半终粉磨系统，增加1台斗提提升入磨物料，增加高效选粉机三次风，改造磨内构件，技改后系统内的粉尘循环量明显降低，磨机台产提升，电耗下降明显，取得了良好的经济效益。 |
| 英文摘要: |
| Our company employs a combined grinding system consisting of a Φ1,500 mm × 1,000 mm roller press and a Ф3.8 m × 13 m closed-circuit ball mill for cement grinding. Since its commissioning in 2011, the system has consistently performed poorly, failing to meet production targets while exhibiting high energy consumption in the cement process. This article outlines the energy-saving technical modifications made to the cement grinding system, which included transforming the double closed-circuit production system into a semi-final grinding system, adding a bucket elevator to lift the feed material into the mill, incorporating a high-efficiency separator with tertiary air, and modifying the internal components of the mill. Following these upgrades, the dust circulation within the system was significantly reduced, the mill's output increased, and energy consumption decreased markedly, resulting in substantial economic benefits. |
