Abstract: With combination of PLC and configuration software, a set of automatic monitoring system for feeding of mill in a dressing plant was established. During the process of adopting the MCGS configuration interface, three kinds of blanking means for fabric belt were proposed for making right choice according to the actual need, including sequential blanking, optimal blanking at fixed level and fuzzy control blanking. Meanwhile, in order to reflect the continuity of the mineral processing production, the discharge from ore bin in mill feed system was arranged in frequency control to achieve the purpose of the constant feeding and to make the ball mill run normally. As well, remote monitoring can be realized by the functions of real-time curve, historical curve and alarm reporting of configuration software.
