Magnetic shielding: application to a new magnetic separator and classifier

In the development of a new magnetic separator and classifier, magnetic shields had to be designed to protect the particles present within the feeding systems, from the influence of the generated magnetic fields. One configuration for the batch mode of operation and three different ones for the continuous mode were designed, all of them presenting a three-layer structure of different magnetic materials. The choice between the three different continuous mode feeding system configurations is done case-by-case based on the magnetic field intensity and in total costs. (C) 2003 Elsevier B.V.
