Wet Drum Magnetic Separator

Wet Drum Magnetic Separator for Mining & Mineral Processing

Product Introduction

Wet Drum Magnetic Separator is a widely used magnetic separation equipment designed for recovering magnetic minerals from slurry materials in mining and mineral processing industries. It is mainly applied for iron ore beneficiation, magnetite concentration, heavy media recovery, coal washing plants, and industrial mineral purification.

As a professional industrial wet drum magnetic separator manufacturer, we provide permanent magnetic drum separators with optimized magnetic circuits, heavy-duty structures, and multiple tank designs to meet different mineral processing requirements.

The equipment uses a rotating magnetic drum with a stationary internal magnetic system. When slurry enters the separation zone, magnetic particles such as magnetite and ferrosilicon are attracted onto the drum surface, while non-magnetic materials are discharged with the slurry flow. This continuous separation process provides high recovery efficiency, stable operation, and low maintenance costs.

Wet Drum Magnetic Separators are commonly classified into Low Intensity Magnetic Separators (LIMS) and high-intensity wet magnetic separators according to magnetic field strength and mineral characteristics. LIMS wet drum separators are widely used for strongly magnetic minerals such as magnetite, while WHIMS (Wet High Intensity Magnetic Separator) is applied for weakly magnetic minerals including hematite, ilmenite, and other fine mineral particles.

Applications of Wet Drum Magnetic Separator

1. Iron Ore Beneficiation

Wet Drum Magnetic Separator is one of the key machines in magnetite ore processing plants. It is widely used for:

• Magnetite ore concentration
• Iron ore roughing and cleaning
• Recovery of iron-bearing minerals from tailings
• Increasing Fe grade of final concentrate

For magnetite beneficiation, LIMS Wet Drum Separator provides excellent selectivity between magnetic and non-magnetic particles, improving concentrate recovery while reducing impurities.

2. Dense Medium Recovery in Coal Washing Plants

In coal preparation and heavy media separation (HMS/DMS) plants, the separator is specially designed for recovering magnetic media such as magnetite and ferrosilicon from diluted slurry.

Applications include:

• Heavy Media Recovery Magnet
• Ferrosilicon Recovery
• Magnetite Recovery Circuit
• Coal Washing Plant Magnetic Separation

The high recovery efficiency helps reduce media consumption and operating costs while maintaining stable density control in the dense medium circuit.

3. Industrial Mineral Purification

Wet Drum Magnetic Separator is also used for removing iron contamination from non-metallic minerals.

Typical applications include:

• Quartz sand iron removal
• Silica sand purification
• Ceramic slurry purification
• Feldspar processing
• Glass sand upgrading

By removing unwanted magnetic impurities, the equipment improves product whiteness, purity, and commercial value.

Tank Design Options

Different slurry characteristics require different tank configurations. Our Wet Drum Magnetic Separator is available in three main designs:

Concurrent Wet Drum Separator

The slurry flow direction is the same as drum rotation direction.

Features:

• Suitable for coarse particles
• High processing capacity
• Commonly used for roughing separation

Typical application:

• Magnetite ore pre-concentration
• Coarse iron ore separation

Recommended feed size:

0.5 mm – 6 mm

Counter-Current Wet Drum Separator

The slurry flows opposite to the drum rotation direction.

Features:

• Higher concentrate grade
• Better recovery of fine magnetic particles
• Suitable for cleaning and finishing operations

Typical applications:

• Fine magnetite concentration
• High-grade iron concentrate production
• Tailings recovery

Semi-Counter-Current Wet Drum Separator

A combination design providing balanced recovery and concentrate quality.

Advantages:

• Excellent separation efficiency
• Flexible operation
• Suitable for most mineral processing plants

Typical applications:

• General iron ore beneficiation
• Multi-stage magnetic separation circuits

Key Advantages of Our Wet Drum Magnetic Separator

1. High Magnetic Recovery Efficiency

Optimized permanent magnetic circuits provide strong attraction force and stable recovery performance for magnetite and ferromagnetic minerals.

2. Heavy-Duty Mining Structure

Designed for continuous operation in harsh mining environments with wear-resistant drum covers and corrosion-resistant components.

3. Multiple Magnetic Intensities Available

Different magnetic field strengths can be customized according to mineral properties:

• Low Intensity Magnetic Separator (LIMS)
• Medium Intensity Magnetic Separator
• High Field Strength Magnetic Drum Separator

Typical magnetic intensity:

300 – 4500 Gauss

4. Wear-Resistant Drum Design

The drum surface can be equipped with:

• Rubber lining
• Polyurethane wear protection
• Stainless steel protection layer

This improves service life when processing abrasive slurry materials.

5. Easy Maintenance & Long Service Life

The simple rotating drum structure reduces moving parts and maintenance requirements, ensuring reliable operation in large-scale mineral processing plants.
