Heavy-Duty Permanent Magnetic Drum Separator & Magnetic Head Pulley for Mineral Processing

A Magnetic Drum Separator is a widely used magnetic separation equipment in mining, mineral processing and recycling industries for separating ferrous materials from non-magnetic materials. Designed for continuous operation under harsh industrial conditions, our permanent magnetic drum separators provide reliable performance for iron ore beneficiation, slag recovery, coal preparation, aggregate processing and metal recycling applications.

According to different installation methods and processing requirements, the equipment can be supplied as a stand-alone drum separator with housing or a magnetic head pulley integrated into conveyor systems. The magnetic head pulley replaces the conventional conveyor head pulley and performs continuous separation during material discharge, removing tramp iron and recovering valuable magnetic minerals without additional power consumption.

With optimized magnetic circuit design, high-quality permanent magnets and heavy-duty structural components, our mining magnetic drum separators deliver stable magnetic force, high separation efficiency and long service life in demanding mining environments.

Working Principle of Magnetic Drum Separator

The Permanent Magnetic Drum Separator works by using a fixed magnetic field generated by permanent magnets inside the rotating drum. When material enters the magnetic field area, magnetic particles are attracted and held onto the drum surface, while non-magnetic materials continue moving forward due to gravity and centrifugal force.

As the drum rotates, magnetic materials are transported to the discharge area and released separately from non-magnetic materials, achieving continuous automatic separation.

For conveyor applications, the Magnetic Head Pulley acts as the drive pulley at the end of the conveyor. When bulk materials pass over the pulley, magnetic minerals are attracted and remain attached to the belt surface, while non-magnetic materials follow their original trajectory and discharge separately.

This design is especially suitable for:

• Iron ore pre-concentration
• Waste rock rejection
• Removal of tramp iron from bulk materials
• Slag recycling
• Aggregate and quarry material purification

Applications of Magnetic Drum Separator in Mining Industry

1. Iron Ore Pre-Concentration & Ore Cobbing

The Ore Cobbing Magnetic Drum is commonly used in the early stage of iron ore processing to remove low-grade waste rock and improve feed quality before grinding.

By upgrading iron ore through magnetic separation, mining operations can:

• Reduce grinding energy consumption
• Increase mill capacity
• Lower transportation costs
• Improve overall beneficiation efficiency

Dry drum magnetic separators are particularly suitable for coarse iron ore particles and pre-concentration applications.

2. Mining Conveyor Magnetic Head Pulley

The Mining Magnetic Pulley is designed for installation on belt conveyors as a self-cleaning magnetic roller system.

Compared with traditional electromagnetic separators, permanent magnetic head pulleys offer:

• No external power supply
• Lower operating costs
• Continuous automatic separation
• Simple maintenance
• Long working life

They are widely used in:

• Iron ore mines
• Coal handling plants
• Quarry operations
• Aggregate production lines
• Recycling facilities

3. Wet Drum Magnetic Separator for Mineral Processing

The Wet Drum Magnetic Separator is mainly used for fine particle separation in mineral processing plants.

Typical applications include:

• Magnetite recovery
• Heavy media recovery
• Iron ore beneficiation
• Tailings recovery

The wet separation process improves recovery efficiency for fine magnetic particles and is widely applied in modern concentrators.

4. Metal Recovery & Recycling Applications

Our industrial magnetic drum separators are also suitable for recovering valuable ferrous metals from:

• Steel slag
• Municipal waste
• Industrial waste
• Foundry sand
• Construction materials

The equipment helps customers reduce material loss and improve resource utilization.
