The Romanian Circuit Board Crushing Separating Line is a compact, high-efficiency PCB recycling project designed to process 100–200 kg/h of mixed electronic waste boards. The system focuses on stable mechanical crushing and precise metal–nonmetal separation, helping the customer achieve high-purity copper recovery and clean, environmentally compliant production.

1. Project Background

The Romanian customer processes:

• Computer motherboards
• Laptop and mobile phone PCBs
• Home appliance control boards
• Mixed small electronic waste

Their goals included:

• A small-to-medium capacity line with stable performance
• High metal recovery purity suitable for resale and refining
• Reduced dust emissions to meet EU environmental requirements
• Easy operation and low maintenance workload

The 100–200 kg/h system was selected to fit their workshop layout and long-term expansion plans.

2. On-Site Equipment Configuration

Motherboard Crushing & Separating Line
(1) Primary Shredding

• Heavy-duty slow-speed shredder
• Efficiently breaks down thick PCBs and multilayer boards
• Low noise and dust control design

(2) Fine Crushing

• Multi-stage crushing system
• Produces 20–40 mesh material for optimal separation
• Wear-resistant blades ensure long service life

(3) Airflow Gravity Separator

• Separates fiberglass, resin powder, and nonmetal materials
• Adjustable airflow for different PCB types

(4) Electrostatic Separator

• Recovers fine copper, aluminum, and mixed metals
• Final metal purity ≥ 98%
• Very low metal loss and high separation precision
• The line ensures clean, continuous material flow from feeding to final metal output.

3. On-Site Performance

After commissioning, the Romanian project achieved:

• 100–200 kg/h continuous and stable capacity
• High metal separation efficiency with minimal copper loss
• Significant reduction in workshop dust due to negative-pressure filtration
• Low power consumption and simple maintenance procedures
• Smooth operation under Romania’s colder climate conditions

The customer reported substantial improvement compared to their previous manual and semi-mechanical processing setup.
