Magnetic separator is most useful for non-electric separator for separating iron from non-magnetic processed in bulk quantity for purity of end product, metal having commercial value. The crushed material from roller crusher which is the mixture of both metal contaminates & sand contaminates now fed through magnetic separator. As the material tod evenly through a vibrating feeder falls over the drum, powerful magnetic field attracts & hold iron particles to the revolving shell & the sand contaminates falls freely from the shell while iron particles are automatically discharged at the other end. The permanent magnets used are everlasting & its strength does not diminish during the normal use.
