Analysis and Simulation of Typical Opening Magnetic Circuits in Magnetic Separators

Opening magnetic circuit is a kind of circuit type having the earliest, wide, mature and innovative application. A comprehensive study of the circuits would be very useful for target circuit design, process flow optimization, and engineering equipment selection. By means of COMSOL Multiphysics FEM software, several typical opening magnetic circuits were simulated and analyzed, and then the relative influencing factors of magnetic source, magnetic pole depth, matching proportion, auxiliary pole and magnetizing direction to the circuits were analyzed. Based on the simulation and analysis the motion trajectories of magnetic particles under several magnetic circuits were described and discussed.
