摘　　要：某4500t/d水泥熟料生产线配套中卸磨原料粉磨系统,随着生产能力的不断提高,粉磨系统产量低、电耗高、主机设备故障率高、设备维修费用高等问题逐渐凸显。提出了将中卸磨系统更换为TRP220-160辊压机终粉磨系统,并配套使用高效组合式选粉机和2×2240kW永磁电机的系统改造方案。从主机设备工艺布置设计,润滑油站、液压站工艺布置设计,控制系统设计和辊压机后期检修维护设计等方面重点介绍了辊压机终粉磨系统改造工艺设计特点。实践应用后,原料粉磨系统产量提高了101~121t/h,电耗降低了8.2~9.2kW∙h/t。The raw material grinding system adopted the middle discharge grinding system in a 4500t/d Cement Clinker Production Line.With the continuous improvement of clinker production capacity,the problems of low output,high power consumption,high failure rate of main equipment and high maintenance cost of equipment were gradually highlighted.Therefore,it is proposed to replace the middle unloading grinding system with the roller press(TRP220-160)final grinding system,and supporting the use of efficient combined separator and 2×2240kW permanent magnet motor system transformation scheme.The process design features of the final grinding system of the roller press are introduced from the aspects of the process layout design of the main equipment,the equipment layout design of the lubricating oil station and the hydraulic station,the design of the control system and the maintenance design of the roller press in the later period.After practical application,the production of the raw material grinding system is increased by 101~121t/h,and the power consumption is reduced by 8.2~9.2kW·h/t.
