Abstract: Summarized the working principle and characteristics of typical high pressure roller mill,grading equipment,powder ore dry magnetic separator. Introduces the structure and possible process of high pressure roller mill-dry classification-low intensity magnetic separation integration system. Characteristics of the technological process and suitable types of iron ore was analyzed. After using high pressure roller mill-dry classification-low intensity magnetic separation integration system in Hami Zhongtian Iron Mine,good sorting index were obtained. High pressure roller mill-dry classification-magnetic separation integration system has advantages of no dressing production water,small occupation,low power consumption,simple process flow,etc.
