Magnetic separator for sale in Nigeria

Magnetic separator is one of the machines with the widest application and highest universality in the mining industry and it is suitable for removing the iron to recycle the powder particles. Magnetic separator for sale in Nigeria, Magnetic separator is widely used for the resources recycling in lumbering, mining, ceramics, chemistry and food industry. It is suitable for the wet type or dry type of magnetic separation of materials whose granularity is smaller than 3mm such as magnetite, pyrrhotite, calcined ore and ilmenite and for the deironing of coal, non-metallic ore, building material and other materials. Magnetic separator for sale in Nigeria, The magnetic system of the magnetic separator usually adopts high-quality ferrite material or combines with rare earth magnet steel. Previously the average magnetic induction intensity of the cylinder surface was 800-4000mT, but with the technical development, this machine can be made in roller shape, and its magnetic field intensity is improved to 8000mT, which is the highest magnetic field intensity in actual.

Introduction:

Magnetic separator is suitable for the wet magnetic separation of the materials whose granularity is below 3mm such as magnetite, pyrrhotite, calcined ore and ilmenite and can also be used for removing iron from the materials such as coal, non-metal ore and building material. The magnetic system of China magnetic separator is a compound of fine ferrite material and rare earth magnets and the average magnetic induction intensity of the surface of the cylinder is 100~600mT. According to specific need, customers can choose from many kinds of magnetic separators with different surface magnetic intensity such as downstream type, semi-reflux type and reflux-type. This product has the advantages of simple structure, big processing capacity, convenient operation and easy maintenance.

Performance Features of Wet Magnetic Separator

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 rawore 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.

Working Principle:

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.
