Magnetic field analysis of high gradient magnetic ...

Oct 01, 2012  Highlights Magnetic field and the gradient decide magnetic forces acting on particles in High Gradient Magnetic Separation (HGMS). We calculated the magnetic field and the gradient by using Finite Element Method (FEM). Firstly, we calculated them through 2 dimensional axis-symmetric analysis. Furthermore, we calculated the magnetic field distribution through 3 dimensional analysis.

Magnetic field analysis of high gradient magnetic ...

Oct 01, 2012  High Gradient Magnetic Separator (HGMS) uses matrix to make high magnetic field gradient so that ferro- or para-magnetic particles can be attracted to them by high magnetic force. The magnetic force generated by the field gradient is several thousand times larger than that by the magnetic flux density alone. So the HGMS shows excellent performance compared with other magnetic separators.

Even though the magnetic field gradient in the separation zone can be as high as approximately 300 T m −1 at the surface of the magnet columns, it decays to 0 T m −1 at the middle of the separation zone. This phenomenon has caused the average magnetic field gradient within the separation zone to be approximately 90 T m −1 .
