Selection of magnetic separators for removing tramp iron

In the selection of magnets for removing tramp iron, factors for initial consideration are the dimensions of the belt conveyor, its speed and the height of the material burden conveyed by the belt. Besides, these, the working gap for defined iron particles, the field configuration and the electric power are also important. The surface temperature and an oil-free cooling system are crucial for operation, as is simple belt replacement. With regard to meeting the high requirements of the mining industry with its expensive conveying and comminution systems, a temperature-stable coil material and a magnetic field extending as far as possible in the direction of material travel should be ensured. Dry magnets that are not filled with oil facilitate maintenance and operation and save costs in the long term.
