摘　　要：针对水泥配料与磨机负荷控制水泥粉磨机这一关键技术问题,选取球磨机为设计对象,采用S7-200PLC作为主控制器,西门子MM420变频器作为调速装置,借助西门子WinCC V7开发工具,设计了一种基于PLC的水泥厂粉磨机控制系统,实现了水泥厂粉磨机在生产过程中对温度、压力和转速等参数的采集、过程控制及质量监控。实践结果表明,设计完成的基于PLC水泥厂粉磨机控制系统,不仅可以直观、清晰显示粉磨机生产工艺流程的各个环节并能进行控制或监控,而且还能对故障进行报警,对于改善工人劳动环境,提高水泥配料自动化水平和水泥粉磨机长期安全运转等具有重要的现实意义。Aiming at the key technical problems of cement mill which are cement ingredients and cement load control, the ball mill is designed as the design object, in which, S7-200 PLC is used as the main control, Siemens MM420 converter is used as a speed control device, and Siemens WinCC V7 is used as a development tool. A PLC-based cement mill pul- verizer control system is designed to achieve the monitor of the cement mill parameter acquisition, such as temperature, pressure and speed, process control and quality control in the production process. The results of the practice show that the PLC-based cement mill control system not only can intuitively and clearly show , control and monitor all aspects of the production process of the pulverizer and control or monitor , but also can check the fault to alarm. It is of great practical significance for improving the working environment of workers, and improving the level of cement batching and the long- term safe operation of cement grinding machine.
