Magnetic Roller

Permanent Magnetic Head Roller for Mining, Recycling and Industrial Conveyor Systems

A Magnetic Roller, also known as a Magnetic Pulley, Permanent Magnetic Pulley or Magnetic Separator Roller, is an efficient automatic separation device designed to remove ferrous metals from bulk materials during conveyor transportation.

Installed at the discharge end of a belt conveyor, the Magnetic Head Roller replaces the traditional conveyor head pulley and provides continuous magnetic separation without additional manual operation. When material passes over the magnetic pulley, ferrous particles are attracted to the belt surface and separated from non-magnetic materials, achieving automatic tramp metal removal and material purification.

Our industrial magnetic rollers are widely used in mining, quarrying, recycling, steel processing, waste management, aggregate production and bulk material handling industries.

With optimized magnetic circuit design, high-performance permanent magnets and heavy-duty mechanical construction, our conveyor magnetic rollers provide reliable operation under harsh industrial conditions, improving product quality and protecting downstream equipment.

Working Principle of Magnetic Pulley

The Permanent Magnetic Pulley uses a fixed magnetic field generated by permanent magnets installed inside the rotating pulley shell.

During operation:

1. Bulk material is transported by the conveyor belt toward the magnetic head roller.
2. Magnetic materials are attracted and held against the belt surface.
3. Non-magnetic materials continue their original trajectory and discharge separately.
4. Magnetic metals are released automatically after leaving the magnetic zone.

This continuous separation process eliminates the need for frequent manual cleaning and provides long-term stable performance.

Compared with suspended electromagnetic separators, a Conveyor Head Roller Magnet offers:

• No external power consumption
• Lower operating costs
• Compact installation structure
• Continuous automatic separation
• Easy maintenance

Applications of Magnetic Roller & Magnetic Pulley

1. Mining and Mineral Processing

In mining operations, Mining Magnetic Rollers are widely installed on belt conveyors to remove unwanted iron materials and recover valuable magnetic particles.

Typical applications include:

• Iron ore processing
• Magnetite recovery
• Mineral beneficiation
• Quarry material purification
• Coal handling systems

The Heavy-Duty Magnetic Pulley helps protect crushers, screens and conveyors from tramp iron damage, reducing equipment downtime and maintenance costs.

2. Recycling Industry

The Recycling Magnetic Pulley plays an important role in separating ferrous metals from recyclable materials.

Applications include:

• Scrap metal recycling
• E-waste recycling
• Municipal solid waste processing
• Plastic recycling
• Construction waste recycling

The self-cleaning magnetic system improves sorting efficiency and increases recovery rates of valuable ferrous materials.

3. Aggregate and Quarry Applications

For sand, gravel and crushed stone production, the Conveyor Belt Magnetic Roller provides effective iron contamination removal before final product shipment.

Benefits include:

• Improved product purity
• Reduced customer complaints
• Protection of processing equipment
• Continuous automatic operation

4. Steel and Industrial Processing

In steel plants and manufacturing facilities, Tramp Metal Removal Rollers are used to remove unwanted iron pieces from raw materials and finished products.

Common applications:

• Steel slag recovery
