Magnetıc Pulleys are widely used in belt conveyors for the continuous and automatic separation of ferromagnetic particles such as iron or steel, and even weakly magnetic particles (such as particles from machined stainless steel) from coarse to fine materials. Magnetic Pulley isintegrated into belt conveyors ensure continuous and automatic separation of contaminated unwanted iron from the system, transported sand, gravel, limestone, recyclable materials, wood products, foodstuffs, chemicals, mines, coal, ceramics, paper, plastic, rubber, etc.

As shown in the figure, Ferromagnetic and anti-ferromagnetic material (Fe and weak magnetics) enters the magnetic field of the drum, the iron is magnetised and held to the belt until it reaches the bottom, out of the magnetic field and discharged separately. The cleaned, non-magnetic material is discharged through the drum in a normal orbit.

Magnetic Drums are manufactured from Ferrite magnets if the ferromagnetic material to be separated has high magnetic sensitivity and from Neodymium magnets if it has low magnetic sensitivity.

Standard Magnetic Drum models also use axially polarized magnets. Radial (diametrically) polarized magnets are preferred for the separation of weak ferromagnetic particles with fine grain size. Here, it is important for the efficiency of the separation that the product is finely fed.

Advantages:

*It is strong and reliable. Magnetic pulleys designed and manufactured by Mıknatıs R&D are made of quality steel stainless tubing with welded dividers to securely hold piles of magnets.

*It can be specially manufactured in full magnetic drums that can operate at high temperatures by using different types of magnets.

*It prevents machine damage and product contamination.

*Automatic cleaning (continuous): It provides automatic separation of iron (Ferromagnetic material -Fe) from the materials carried by the conveyor, there is no need for continuous cleaning of the magnetic equipment.

*Cost-effective: Magnetic pulleys are practically maintenance-free and since these magnets are integrated into an existing installation, there are virtually no extra operating and energy costs.
