3D FEA of the Performances of Magnetic Separator for Different Drum Topologies

The separators performances and process are improved by new recovering technologies based on separation theories, model of force and magnetic field nature. However, numerous electrostatics and magnetics separators generate the electromagnetic field, these separators are classified on the kind of recovered particles: nonmetallic, metallic or nonferrous. The separators development are based on the configuration size and magnetic source based on electromagnet or permanent magnet: intensities, form, number, orientation. In this study, two magnetic separators are proposed with two configuration of drum, the buried magnet drum and the surface magnet drum respectively. The paper aim is to study using the 3D Finite Element Analysis to compare the effectiveness and the performance of the separator in the presence of aluminum particle near the two configuration of separator to show the magnetic effect, induced current and ejection force. The FEA results illustrate the effect of configurations of eddy current separator on separation parameters. These results can help to optimize the size and magnet position of new magnetic separator.
