The second and third concentration plant 7.5 million t/a beneficiation process automatic control system:
Due to the harsh environment of the scene and the quantity of dust is large. To overcome the negative factors of high dust and strong electromagnetic interference, on-site control box and control systems have done a lot of optimization, realization of crushing plant equipment interlocking start-stop, fault alarm, parking and other automation control system. Thoroughly solved the problems in hardware connection, maximum limit reduces the failure rate, increase the reliability and stability of the equipment operation. Completely avoid the production failure caused by wrong operation, site operation and inspection is greatly reduced, ensure the safety in production, achieve the ultimate goal of the pursuit of mine automation control equipment for efficient operation of workers and increase efficiency. Because the operation is simple, safe and reliable, our control scheme has been implemented in several large mines, and have been achieved very good results. It is now vigorously promoted, other mines are in the implementation of the transformation.
Grinding process adopts double closed loop PID fuzzy control algorithm, to improve the reliability and accuracy of the control and improve the average daily capacity of mill by more than 10%.
From the overall of crushing, grinding, after the introduction of automation 267000 yuan can be saved for power consumption a year, 480000 yuan to reduce workers' wages, improve the efficiency of the production increase of 7.82 million yuan.
Total investment of automation of in 5.3 million yuan, maintenance cost is about 300000 yuan a year, so we can recycling cost in one year, and mill plant within the length of service benefit every year.
