Abstract

Abstract

The important role of stirring fine grinding technology in the process of fine grinding and ultra-fine grinding in mineral processing industry was expounded. The vital advantage and application area of the screw, disc and rod fine grinding agitators are analyzed in detailed. Theoretical analysis of key factors of fine grinding effect and simulation processes and results based on CFD, DEM and PEPT were discussed emphatically. Also, the research progress of stirring fine grinding technology was analyzed. Then, the typical structure, research, development and application progress of fine grinding equipments represented by three agitators mentioned above were summarized, so as to give a hand to the research and popularization of stirring fine grinding technology and equipments. And, they can provide useful references to the realization of energy-saving and efficient fine grinding and ultra-fine grinding in mineral process industry.
