Design and application of intelligent control system for iron polymetallic concentrator

The digital mineral processing control system not only guarantees the process flow and the stable operation of the equipment, but also improves the anti-interference ability and self-adaptation ability of the production system. Through the long-term mining and analysis of production data, the iterative optimization of production process operation mode is realized. This paper mainly designs and implements the intelligent control system for the grinding and flotation process of an iron polymetallic concentrator. Through the grinding intelligent control system, the optimization control instructions are issued to the ore feeding, water replenishment and frequency modulation circuits of the basic automation unit, which stabilizes the production process and improves the quality of overflow products; The flotation intelligent control process improves the stability of the operation process, optimizes the process yield and stabilizes the concentrate grade through on-line particle size analysis and intelligent inflation control system.
