Secondary poles are set up at theedges of the magnetic discs, causingmagnetic particles to stick to the ar-mature until beyond the primarypoles and until the neutral point isreached, when the material changespolarity, and, in so doing, falls offinto a receiver below. The waste falls direct off the armature into aseparate hopper. The capacity of these machines islarge, as much as 400 tons havingbeen treated in twenty-four hours. Fig. 3 shows details of revolvingarmature with alternate plates ofmagnetic and non-magnetic material,as used in the Wetherill Type F Sep-arator. The Edison separator consists of anumber of bar
