The Vietnam Circuit Board Recycling Line is a turnkey e-waste processing project designed to handle mixed waste PCBs from computers, mobile phones, consumer electronics, televisions, home appliances, and industrial control boards. This case showcases our ability to deliver a high-efficiency, environmentally compliant recycling solution that maximizes metal recovery while ensuring stable operation under Southeast Asia’s humid climate conditions.

1. Project Background

The Vietnamese client, a growing e-waste recycling company, required a complete PCB recycling solution capable of processing 300–500 kg/h of mixed printed circuit boards. Their goals were:

• Achieve high separation purity of copper, and resin powder
• Meet Vietnamese environmental emission standards
• Reduce manual labor and improve safety
• Build a stable, easy-to-maintain plant suitable for long-term expansion

After technical evaluation, we provided a fully automated Circuit Board Recycling Line equipped with dust control, negative-pressure feeding, and an optimized crushing–separation system.

2. On-Site Installation Overview

The entire production line is arranged compactly to fit the customer’s existing factory space, while maintaining smooth material flow. The on-site layout includes:

(1) Primary Shredding Section

• A heavy-duty shredder breaks down whole PCB boards into smaller fragments.
• Handles computer motherboards, TV boards, CCL sheets, and mixed electronic scraps
• Slow-speed, high-torque design reduces dust and avoids metal loss

(2) Fine Crusher & Pulverizing System

• Multiple-stage crushers reduce material to a controlled particle size , preparing it for separation.
• Low-noise chamber
• Wear-resistant knives
• Intelligent load balancing to prevent clogging

(3) Airflow + Electrostatic Separation System

• This is the core process of the line.
• Airflow separator removes lighter resin powder and fiber
• Electrostatic separator achieves high purity metal separation
• Final metal purity reaches ≥ 98%, ensuring maximum economic return

(4) Pulse Dust Collection & Negative Pressure System

• Vietnam’s environmental regulations require clean emissions.
• Complete dust capture from shredding to separation
• Pulse jet filters ensure the workshop remains dust-free
• Negative pressure prevents fugitive emissions

(5) Central Control Panel

A PLC-based intelligent control system manages all motors, feeders, separators, and dust collectors.

Operators can monitor the system status and alarms in real time, ensuring safe and reliable performance.
