Study on PCS7 Heavy Plate Feeder automation control system

Aiming at problems in the secondary crushing system of a concentrator crushing plant, such as the old-fashioned control mode of heavy plate feeder control system, overload and under-load conditions of the mechanical equipment, large labor intensity of the operators, control lag, and low production efficiency, the research is done on automation design of heavy plate feeder in the secondary crushing system of the crushing plant. The proposed method is to adopt PCS7 system to make automatic detection, control the start-stop and the speed of SIEMENS converter which is used to drive the heavy plate feeder, and use WINCC to design the monitoring picture of the secondary crushing system. The research shows that, with automatic control based on WINCC and PLC, the system becomes flexible, convenient, and stable, and the overload and under-load conditions are eliminated, which further results in lower failure rates. In practical application, through continuous optimization of the improved automatic control system of the heavy plate feeder, better performance on stability, accuracy and failure rates is obtained.
