Plate-type magnetic separator is a kind of new dry pretreatment equipment,developed by University of Science and Technology Beijing,applicable to poor magnetic ore at 20 mm or below. Magnetic system in plate-type magnetic separator is optimized by A. M. software. It is determined that magnetic block brand of NdFeB is N50,thickness 30 mm,vertical clearance 40 mm,Q235 for the magnetic backplane;On the base of simulation results,the measured magnetic induction intensity of phys-ical model is closed to the simulated results,that is,the simulated results has good reliability. Results show that using computer software to simulate the magnetic field distribution of magnetic system can greatly reduce the workload and improve the reliabil-ity of the magnetic system design.
