Abstract: On the basis of introducing the important effect of wet fine grinding technology in the process of fine grinding in the mineral process field, analyzing the wet fine grinding prototype of the screw, rod. Theoretical analysis of energy dissipation, grinding media motion of wet fine grinding and simulation processes and results based on CFD, DEM and PEPT were discussed emphatically. Also, the research progress of wet fine grinding technology and equipment were analyzed. Then, the typical structure research, technical optimization, development and application progress of wet fine grinding technology and equipment were summarized, so as to give a hand to the research and popularization of wet fine grinding technology and equipment. And, they could lay a foundation for the realization of energy-saving and efficient fine grinding and ultra-fine grinding in mineral process industry.
