摘　　要：研制一种HRM型外循环立式磨作为全外循环生料终粉磨系统主机设备,自身不带任何选粉装置,经磨辊粉磨过后的物料全部外排,系统采用机械提升的方式将从磨内排出物料提至V型选粉机,细物料经V型选粉机后进入高效动态选粉机分选,粗颗粒回立磨继续粉磨。工业实践证明,全外循环立式磨生料粉磨系统的单位电耗比风扫式内循环立磨系统单位电耗低3.5~4kWh/t;对于水泥生产装备技术及粉磨工艺来说,该项目的研究内容和研究方向具有重大意义。This study endeavors to introduce the development of a HRM type external circulating vertical mill as the host equipment of the full external circulating raw material final grinding system,itself without any classifying device,the material after grinding by the grinding roller will be all discharged,the system uses mechanical lfting to lif the material discharged from the mill to the V-type classifier,fine material afier selection through V-type classifier will go into the high efficiency dynamic classifier for sorting,and coarse particles willgo back to the vertical mill to continue grinding.Industrial practice has proved that the unit power consumption of the full external circulating vertical mill raw meal grinding system studied in this project is 3.5~4kWh/t lower than that of the airswept internal circulating vertical mill system;for cement production equipment technology and grinding process,the research content and research direction of this project are extremely significant.
