Research Of The Hybrid Control System In Grinding And Classification

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.
