Magnetic Properties of Spherical Collectors in a Transverse Magnetic Filter

A transverse magnetic filter was designed and built. The magnetic properties of spherical collectorsused in the filter were discussed. The magnetic filtration experiments were performed with Fe powder,used as magnetic particles, suspended in fluid flow in the direction perpendicular to an external uniformmagnetic field between 0 mT and 109 mT. In this work, the collectors with different sizes: diameters of3.455 mm, 4.789 mm or 6.369 mm were used to capture the magnetic particles coming to the filter. Themagnetic properties of the collectors were discussed in filter efficiency terms versus the previousapplied filed. By comparison, experimental results show that the filter efficiency of a lower diameter isgreater than that of a higher diameter.
