摘　　要：随着国家节能减排政策的相继出台,水泥粉磨系统的能效提升变得尤为迫切。常规水泥辊压机联合/半终粉磨工艺技术存在物料与系统不兼容、系统与设备不匹配且缺乏可调节性等技术难题。鉴于此,创新研发了基于“物料-系统-设备”耦合理念的在线调节柔性粉磨工艺与带沉降室的侧进风高效选粉装备等节能低碳技术,并已成功应用于多个工业项目。工业应用实践表明,采用“大辊压机+小球磨机”的水泥辊压机联合粉磨系统,在“超低阻力、超低风量、超高浓度”的运行模式下,能够显著提高系统产量,降低工序电耗,保证水泥产品性能。相比国家一级能耗限额标准,每吨水泥平均节电幅度高达5.1k W·h,已达到国际领先水平,为水泥行业实现碳达峰、碳中和目标提供了有力支撑。With the introduction of national energy conservation and emission reduction policies,the improvement of energy efficiency of cement grinding system has become particularly urgent.The conventional cement roller press combined/semi-final grinding process technology has some technical problems,such as incompatibility between materials and systems,mismatch between systems and equipment,and lack of adjustability.In view of this,energy-saving and low-carbon technologies such as online adjustable flexible grinding process based on the coupling concept of "material system equipment" and high-efficiency powder selection equipment with side inlet air with settling chamber have been innovatively developed,and have been successfully applied to many industrial projects.Industrial application practice shows that the cement roller press combined grinding system with "large roller press+small ball mill" can significantly increase the system output,reduce the process power consumption and ensure the performance of cement products under the operation mode of "ultra-low resistance,ultra-low air volume and ultra-high concentration".Compared with the national first-class energy consumption quota standard,the average power saving per ton of cement is as high as 5.1k W·h,which has reached the international leading level,providing strong support for the cement industry to achieve the goal of carbon peak and carbon neutralization.
