Abstract:The magnetic separation equipment finds extensive application in separation of materials with magnetic differences, and constitutes the foundation for realization of magnetic separation technology. With the development of magnetic separation equipment, permanent magnetic separators are featured by low energy consumption, simple operation and maintenance, light weight, small size, and stable performance, and have broader development prospects compared with electromagnetic separators. Domestic and foreign experts and scholars have done a tremendous amount of work on permanent magnetic separators and made greater progress. By focusing on the structure, product specifications and control methods of permanent magnetic equipment, this paper gives brief summary of the development trend of domestic and foreign permanent magnetic drums, permanent drum magnetic separators, permanent roller magnetic separators, and high gradient permanent magnetic separators, and looks into the research and development of future permanent magnetic separation equipment.
