| A novel design of a continuously operating repulsive force mode wet high gradient magnetic separator (RMMS) is presented. The method utilizes strong repulsive magnetic forces generated by a two-wire system placed into a permanent magnet’s background magnetic field and a separation channel with one inlet and three outlet streams. The design permits an easy way to scale up the separator by a matrix arrangement of both wires and separation channels. The influence of system parameters on the separation efficiency have been examined experimentally using synthetic magnetite microparticles in water as a model system. In addition a model will be presented that allows the theoretical description of 3D-particle movement in the RMMS system. From the calculated trajectories separation efficiencies can be determined by a statistical approach. |
