| Magnetic separator is a magnetic machine, which is widely used in recent years. It can be used in metallurgy and other industries such as mineral separation, eliminate impurity and so on. It also can be used as special equipment for reclaiming heavy-medium. Because traditional cylinder magnetic separator has the advantages of low operation cost, stable operation, fit for locale production, it takes up irreplaceable position in magnetic separators.We analyzed the force of magnetic separator reclaiming magnetism mineral grain in the condition of callback heavy-medium. We calculated magnetic intensity based on electromagnetic vector potential finite-element-method, established mathematics model of magnetic system, and studied effect of different magnetic system configurations.Magnetic circuit is the main portion of magnetic separator. It decides the performance of magnetic separator. Magnetic system is open-ended. The paper studied the impact of magnetic system height, breadth, radius, number of poles, magnetic difference of potential, pole span, ratio of magnetic pole breadth and airspace breadth, shape of magnetic pole, distance of magnetic pole to the magnetic field's center, calculated parameter of magnetic system, analyzed and certification different action of different magnetic series, designed a kind of permanent magnet cylinder magnetic separator with advanced construction, simple constitution, working reliable .Finally, emulated the magnetic circuit, established mathematics model, calculated magnetic field characteristic with OPERA, so that to analyze the magnetic circuit simply. |
