Abstract: The stirred mill is a high-efficiency ultra-fine grinding equipment,which is widely applied in the field of fine and ultra-fine mineral grinding.This paper elaborates on the innovation course and application status of research on stirred mill equipment.It focuses on introducing the characteristics of various mineral-processing stirred mills,including vertical screw stirred mills (tower mills and vertical mills),horizontal stirred mills,vertical bar stirred mills,vertical high-intensity stirred mills,large-scale double-tank high-intensity stirred mills and large-scale ultra-fine stirred mills,as well as their application in metal mines.Besides,a comprehensive review and development prospects are presented.It is pointed out that the future devel opment directions of mineral-processing stirred mills lie in equipment maximization and integration,intellectualization,green and low-carbon development,as well as precise mineral liberation and mineral micronization.
