Electrostatic Separators

Professional Electrostatic Separation Equipment for Dry Material Processing

Electrostatic Separator is an advanced dry separation technology widely used in recycling, mining, mineral processing and industrial material purification. By utilizing the difference in electrical conductivity, dielectric properties and surface charging characteristics between different materials, the equipment separates valuable materials efficiently without water or chemical additives.

Compared with traditional wet separation methods, electrostatic separation provides an environmentally friendly and cost-effective solution with lower operating costs, reduced water consumption and easier material recovery.

Our industrial electrostatic separator systems are designed for high-efficiency separation of mixed plastics, electronic waste (E-waste), copper and plastic mixtures, aluminum-plastic materials, mineral sands, quartz, feldspar, fly ash and other fine dry materials.

With advanced high-voltage electric field technology, adjustable electrode systems and optimized feeding design, the separator can achieve high purity separation performance for various industrial applications.

Working Principle of Electrostatic Separator

Electrostatic separation is based on the different electrical characteristics of materials. During operation, materials are charged through corona charging or triboelectric charging before entering a high-voltage electrostatic field.

When different particles pass through the electric field, they experience different electrical forces according to their conductivity and charge properties. Conductive materials and non-conductive materials move in different trajectories and are collected separately.

The main separation methods include:

Corona Electrostatic Separation

Corona Electrostatic Separator uses high-voltage corona discharge technology to charge particles selectively. Conductive materials lose their charge quickly and move differently from non-conductive materials.

It is widely applied in:

• Metal and plastic separation
• PCB recycling
• Copper recovery from electronic waste
• Mineral beneficiation

Triboelectric Separation

Triboelectric Separator uses friction charging technology. When different materials contact and separate from each other, they obtain different electrical charges due to different electron affinities.

This technology is especially suitable for:

• Mixed plastic separation
• ABS/PS/PP plastic sorting
• Plastic recycling plants
• Waste electrical equipment recycling

Roll / Drum Electrostatic Separation

Roll Electrostatic Separator uses rotating drums and high-voltage fields to separate fine mineral particles according to conductivity differences.

Typical applications include:

• Heavy mineral sands processing
• Titanium ore separation
• Zircon and rutile upgrading
• Quartz and feldspar purification

Wide Applications of Electrostatic Separation Technology

1. Plastic Recycling and Waste Plastic Separation

Electrostatic plastic separator is one of the most effective technologies for separating mixed plastics with similar densities but different electrical properties.

In plastic recycling industries, traditional density separation methods often struggle with materials having close specific gravity. Electrostatic separation provides a dry solution for separating:

• ABS and PS plastics
• PP and PE materials
• Engineering plastics
• Mixed plastic flakes from waste products

Advantages:

• No water consumption
• High purity plastic recovery
• Reduced wastewater treatment cost
• Suitable for continuous industrial operation

2. E-waste Recycling and PCB Recycling

With the rapid growth of electronic waste, efficient metal recovery technology has become increasingly important.

Electrostatic separation equipment is widely used in E-waste processing lines for recovering valuable metals from:

• Waste printed circuit boards (PCB)
• Electronic components
• Cable recycling materials
• Copper-plastic mixtures

The separator can effectively separate:

• Copper particles
• Aluminum particles
• Plastic materials
• Non-metallic residues

It improves resource utilization and supports environmentally sustainable recycling.

3. Copper Plastic Separator for Wire Recycling

Copper plastic separation is a key process in cable recycling.

After crushing and granulating waste cables, the mixture usually contains copper particles and plastic insulation materials. Electrostatic separators use conductivity differences between copper and plastic to achieve efficient separation.

Applications include:

• Scrap wire recycling
• Cable granulator production lines
• Copper recovery plants
• Waste electrical equipment recycling

Benefits:

• High copper recovery rate
• Clean separation
• Dry processing
• Low maintenance requirements
• 

4. Mineral Processing and Mining Applications

Electrostatic separation technology is increasingly used in mineral processing, especially in areas where water resources are limited.

Dry electrostatic separation provides an alternative solution for mineral beneficiation, including:

• Heavy mineral sands
• Titanium minerals
• Zircon
• Rutile
• Quartz sand
• Feldspar
• Fly ash processing

For mining companies located in arid regions, dry separation technology reduces water dependency and lowers environmental impact.
