Three Disc Dry Magnetic Separator

High Intensity Dry Magnetic Separator for Ilmenite, Monazite, Tungsten, Tin Ore and Quartz Purification

Three Disc Dry Magnetic Separator is a high-intensity magnetic separation equipment specially designed for the dry beneficiation of weakly magnetic minerals, rare metal ores, and non-metallic minerals. It is widely used in mineral processing plants for separating ilmenite, monazite, tungsten, tin ore, tantalum-niobium ore, chromite, zircon, rutile, quartz sand, feldspar, and other minerals with different magnetic susceptibilities.

Unlike wet magnetic separators that require water-based slurry processing, the Three Disc Dry Magnetic Separator operates under a completely dry separation process, making it an ideal solution for mining areas with limited water resources, such as Africa, South America, Central Asia, and desert regions. The equipment achieves efficient mineral upgrading by utilizing adjustable electromagnetic fields generated by three independent magnetic discs.

With adjustable magnetic intensity up to 20,000 Gauss, this Disc Type Dry High Intensity Magnetic Separator provides precise separation performance for fine particle minerals, especially materials with particle sizes below 2–3 mm. By adjusting excitation current, disc height, and separation distance, operators can optimize the magnetic force according to different mineral characteristics and achieve high recovery rates and improved concentrate grades.

Working Principle of Three Disc Dry Magnetic Separator

The Three Disc Dry Magnetic Separator separates minerals according to differences in magnetic susceptibility. The raw material is evenly fed into the separation zone through a vibration feeder. When mineral particles pass through the magnetic field area, magnetic particles are attracted by different magnetic forces, while non-magnetic materials continue to discharge naturally.

The machine consists mainly of feeding system, conveyor belt, three electromagnetic discs, magnetic adjustment system, and discharge units. Each magnetic disc generates different magnetic field intensities:

• The first disc usually works under a lower magnetic intensity to remove strongly magnetic minerals.
• The second disc provides medium magnetic intensity for recovering weakly magnetic minerals.
• The third disc works under a high magnetic field to capture fine weak magnetic particles.

This multi-stage magnetic separation design allows one-time separation of different magnetic minerals from complex ore mixtures, improving mineral recovery efficiency and reducing downstream processing costs.

Applications of Three Disc High Intensity Dry Magnetic Separator

Ilmenite and Titanium Ore Separation

Three Disc Dry Magnetic Separator is one of the preferred solutions for ilmenite beneficiation. It effectively separates titanium-bearing minerals from non-magnetic gangue minerals and improves titanium concentrate grade.

Typical applications include:

• Ilmenite Dry Magnetic Separation
• Titanium Ore Beneficiation
• Rutile and Zircon Separation
• Heavy Mineral Sand Processing

Monazite and Rare Earth Mineral Processing

Rare earth minerals usually have weak magnetic properties and require high-intensity magnetic fields for effective separation. The adjustable magnetic field of this equipment makes it suitable for:

• Monazite concentration
• Xenotime separation
• Rare earth ore upgrading
• Beach sand mineral processing

Tungsten, Tin and Tantalum-Niobium Ore Separation

For complex rare metal ores, Three Disc Dry Magnetic Separator can separate valuable minerals based on magnetic differences.

Applications include:

• Tungsten ore separation
• Tin ore upgrading
• Coltan (Columbite-Tantalite) processing
• Tantalum and niobium enrichment

Non-Metallic Mineral Purification

Besides metal mineral beneficiation, this machine is widely used for removing iron impurities from industrial minerals.

Typical applications:

• Quartz Sand Iron Removal
• Feldspar Purification
• Kaolin Dry Magnetic Separation
• Ceramic Raw Material Processing

It helps improve whiteness, purity, and commercial value of non-metallic minerals.

Advantages of Three Disc Dry Magnetic Separator

1. High Intensity Magnetic Field

The equipment adopts electromagnetic technology and can generate high magnetic intensity up to 20,000 Gauss, suitable for separating weakly magnetic and fine-grained minerals.

2. Adjustable Magnetic Field Control

The magnetic intensity of each disc can be independently adjusted according to different mineral properties, providing flexible separation solutions for various ores.

3. Dry Processing Without Water

The dry separation process reduces water consumption and eliminates slurry treatment requirements, making it suitable for water-scarce mining regions.

4. Multi-Stage Separation Performance

Three magnetic discs provide different magnetic field strengths, allowing separation of strong magnetic, weak magnetic, and non-magnetic minerals in one operation.

5. Suitable for Fine Particle Minerals

Designed for fine mineral processing, it performs efficiently on feed materials with particle sizes generally below 2–3 mm.
