【摘要】 磨矿分级作业是选矿厂非常重要的工艺流程，其效率和产品的质量关系到整个选厂的经济效益。本文以湖北三鑫金铜股份有限公司选矿厂磨矿分级流程为背景，认真研究了给矿、球磨机、分级机、水力旋流器各个部分的工作运行特点及工作影响因素，并根据各部分的工艺特点，设置合理现场的测控点和根据测控点的特点选择不同型号的仪表。同时，根据控制回路的特点及相关性，选择不同的控制方法，如简单的回路采用智能PID控制，复杂的回路采用串级控制等。这样的控制策略既可以避免不必要的程序冗余，又合理的利用了硬件资源，还可以节省工程的投资，而且在实际的工程中已经取得良好的控制效果。控制系统设备的启停、控制参数的设定、控制方式的选择都可在上位站进行操作，控制系统还具有多媒体功能。控制系统以上位主机作服务器，采用网页发布方式，通过现场的以太网实现控制系统的远程监控。本论文的研究成果在湖北三鑫金铜股份有限公司磨矿分级流程进行了应用。生产运行结果表明，本控制系统功能强大、性能可靠、操作方便，取得了显著的经济效益和社会效益。更多还原

【Abstract】 The grinding and classification is all-important arts and crafts in concentration plant, its efficiency and product quality are bearing plants throughout the economic benefits.Based in Hubei Sanxin Gold & Copper Limited—Liability Company, concentrator grinding classification process as a backdrop to seriously study the ore feeding, ball mill, classifier, hydrocyclone various parts of the operating characteristics and the influence of factors, and on the part of the technological features, set reasonable control of the scene under the control point and point to the characteristics of different types of instruments. Also, under the control loop characteristics and the relationship between choice of different control methods, such as simple intelligent PID loop control smart, complex circuits using cascade control. This control strategy is to avoid unnecessary redundancy procedures, and reasonable use of hardware resources, also can save the investment, but also in the works have already achieved good control.The article also from the practical point of view, under the control of the system characteristics of the hardware configuration and software development. Control system uses distributed control system (DCS), under-use mainframe Mitsubishi Q02 PLC, Host China research using mainframe computer industry. Under-used software development Mitsubishi GX 7.0, the software used upper-controlled companies "Kingview" of software development. Equipment Control System Commitment, the control parameter settings, the choice of control in the upper station can operate, control system also has multimedia functions. Over-control systems for mainframe servers, using web publication, Ethernet through the scene of the control system with remote monitoring.In this paper, the results of research in Hubei Sanxin Gold & Copper Limited—Liability Company grinding classification process the application. Production results show that the control system of powerful, reliable and easy to operate, made remarkable economic and social benefits.更多还原
