circuit boards crusher and separator unit features
Intelligent Automated Control System
The entire line employs a PLC-programmed automated control system equipped with a human-machine interface touchscreen. This enables centralized control, real-time monitoring, and parameter adjustment, ensuring user-friendly operation and reducing labor costs.
Multi-Stage Combined Crushing System
Features a multi-stage crushing structure comprising a shredder + hammer crusher + water-cooled grinding mill. This achieves more uniform material particle size, ensuring reliable high-precision sorting in subsequent processes.
Circulating Water-Cooling Design
A circulating water-cooling system is integrated both inside and outside the grinding chamber. This effectively controls equipment temperature rise, prevents resin melting and adhesion caused by high temperatures, and enhances separation efficiency and equipment lifespan.
Efficiency Environmental Dust Collection System
Configured with a negative pressure feeding system and pulse-jet dust collector, achieving over 99% dust removal efficiency. This significantly improves the working environment and meets environmental emission standards.
High-Precision Sorting Technology
Combines airflow density separation with electrostatic separation for thorough separation of metal and non-metal powders, achieving metal recovery rates exceeding 99%.
Compact Structure and Rational Layout
Optimized circuit boards crusher and separator line design ensures efficient space utilization, stable operation, and easy maintenance, making it ideal for large-scale continuous production.
PCB crushing and sorting line Processing Flow
The raw material for this production line consists of circuit boards dismantled by PCB electronic component dismantling machines.
The overall process flow of this printed circuit boards crusher and separator recycling production line is as follows:
- Feeding system: waste circuit boards enter the shredder via the conveyor system.
- Shredding (Shredder): initial crushing of large circuit board pieces.
- Hammer crusher: further reduction of material into smaller particles.
- Water-cooled milling: fine grinding is performed via a water-cooled circulation system, with particle size controlled by a rotary screen.
- Air separator: preliminary separation of metals and non-metals is achieved using density differences.
- Electrostatic sorting machine: achieves high-precision separation of metal and resin powders based on differences in conductivity.
- Dust removal system: maintains negative pressure dust extraction throughout the process to ensure environmentally compliant production.
Final Output:
- Metal powder
- Non-metallic powder (resin powder)
