Magnetic Roller

What is Magnetic Roller?

Magnetic Roller,also called Dry Magnetic Separator, is a kind of equipment used for material sorting, its internal structure includes feeding device, drum, magnetic core, casing and transmission device, during the working process the magnetic core is fixed and immobile, and the motor drives the drum to rotate through the turbine reducer, so as to realize the separation of the impurities and grains.

Usually installed on the transportation belt, when the material passes through, the magnetic material will be attracted to the top of the roller and automatically fall off, while the non-magnetic material will fall along the horizontal parabolic trajectory directly, thus realizing the separation. The permanent magnetic pulley adopts high performance hard magnetic material to form a composite magnetic system, which can be installed in the head of the belt conveyor instead of the main wheel.

If you are a beginner and do not know about Magnetic Roller, tell us your raw material characteristics, finished product requirements, site conditions, production budget, hourly production, and other requirements, we have professional engineers to equip you with a suitable model at a reasonable price. Next, let’s see the types of Magnetic Roller we can supply.

What Is Magnetic Roller Used For?

Magnetic Roller is used for dry pre-sorting of magnetite ore before entering the mill, and the size of entering the mill is below 300mm. Often can be appropriate amount of tailing, to improve the grade into the mill to the geological grade above.Widely used in cement, building materials, mining, steel and other industries

For example, An iron ore concentrate beneficiation plant, poor iron ore after coarse crushing and medium crushing for magnetic separation, want to achieve the effect of restoring the grade, energy saving and production. After the guidance of Chunlei technicians, the permanent magnetic Roller magnetic separator was selected to reduce the load of the next process. Layout of two sections of magnetic separation, magnetic field strength, magnetic separation effect is very obvious, the production efficiency has been improved; can also be used to deal with tailings, conducive to the reuse of equipment, cost savings, and improve the grade.

Working Principle of Magnetic Roller

Magnetic roller is usually used as the drive roller of the transportation belt, when the material passes through the magnetic roller on the transportation belt, it will be sorted out, the magnetic material will be attracted when it moves to the top of the roller, and it will fall off automatically when it turns to the bottom, while the non-magnetic material will fall down directly along the horizontal parabolic trajectory, and the magnetic material and the non-magnetic material will be entered into different receiving hoppers respectively.

Advantageous features of Magnetic Roller

• The magnetic system of the strong magnetic roller all adopts NdFeB magnets with high magnetic energy product and high coercive force, which has high magnetic field strength and large depth of action.
• Dry magnetic separator magnetic field strength for many years demagnetization rate is not more than 5%.
• The magnetic system is wrapped with non-conductive stainless steel to ensure that the magnet does not fall off.
• This strong magnetic roller cylinder adopts non-conductive stainless steel and wrapped with wear-resistant rubber, the service life of the cylinder is significantly improved.
• Permanent magnetic roller can be used as both active and driven roller.
