New Progress in Automation Technology for Beneficiation

The automation of industrial beneficiation process can improve the throughput per unit per hour of crusher and mill and the labor productivity, reduce the energy and raw material consumption and the labor intensity, and increase and stabilize the product quality. The research of beneficiation automation technology involves the complete set of comprehensive control technology for crushing, grinding and classification, dewatering and infiltration and tailing transportation. The paper describes the new progress in the automatic control technology of beneficiation process such as the main parameter detection and control of crushing, the control strategy for grinding, the control strategy for flotation process and the automatic detection and control of the process parameters of high efficiency thickener. The advance in the special detecting instruments for beneficiation automation is also presented such as computer visualizer of flotation, on-line particle size analyzer and on-line grade analyzer.
