The pulp flows into cell body from the pulp box, and under the water flow of the feeding spray pipe, the mineral grain will go into the feeding area of the cell body in the loose condition. In the magnetic field, the magnetic ore particles will have magnetic gathering and form magnet group or magnet chain which is influenced by the magnetic force inside the pulp and moves to the magnetic pole and finally is absorbed onto the cylinder.

Since the polarity of the magnetic pole along the rotary direction of the cylinder is alternately arranged and is fixed during the working process, when the magnet group or magnet chain rotate with the cylinder, it will have magnetic mixing due to the alternation of the polarity, as a result of which, the non magnetic ore such as gangue mixed up with the magnet group or magnet chain will split away off in the stirring, and the magnet group or magnet chain that is finally absorbed onto the surface of the cylinder is concentrate. The concentrate rotates to the edge of the magnetic system where the magnetic force is the weakest along with the cylinder, and under the water flow of the discharging spray pipe, it will be discharged to the concentrate chute. If the roller is all magnetic roller, the ore discharging is completed by brush roll. The non magnetic and weak magnetic minerals are kept in the pump and are discharged from the chute with the pulp to become tailing.
Performance Characteristics
1. The coarse separation of the lean iron ore after coarse crushing or medium crushing eliminates the barren rocks such as surrounding rock, improves the taste of the iron ore and eases the load of the next procedure.
2. Magnetic separator can be used in the closed circuit firing work for restoring the hematite, and it can separate the raw ore that are not fully restored and return it for firing again.
3. In the ceramic industry, magnetic separator can remove the iron mixed in the petuntse and improve the quality of the ceramic product.
4. Magnetic separator can also be used in coal firing, sand making, refractory and other industries that need deironing.
