电子废物/PCB 回收系统 - 可持续资源再利用的解决方案
解决方案背景
印刷电路板（PCB）通过支撑和连接电子元件，在现代电子设备中发挥着至关重要的作用。然而，随着技术的飞速发展和电子产品消费量的不断增长，废弃印刷电路板的数量急剧增加。这不仅浪费了宝贵的资源，还造成了严重的环境污染。.
多氯联苯含有有害物质，包括铅、汞和各种稀有金属。如不妥善处理，这些物质会渗入土壤和水中，对环境和人类健康造成重大风险。因此，加强多氯联苯的回收和再利用至关重要。它不仅可以减轻电子废物对环境的影响，还与全球促进环境保护和资源可持续利用的努力相一致。.

适用材料
FEATURES
High Metal Recovery Efficiency
Engineered to maximize the recovery of copper and precious metals from printed circuit boards. Through optimized crushing, gravity separation, and electrostatic sorting, the system achieves high metal purity and minimizes valuable material loss, improving overall recycling profitability.
Advanced Multi-Stage Separation
The recycling line integrates shredding, fine milling, air classification, gravity separation, and electrostatic technology. This multi-stage process ensures effective liberation of metal from resin fiber, delivering clean copper granules and non-metallic fractions suitable for further reuse.
Stable and Controlled Particle Size
Precise crushing and screening modules maintain consistent particle size distribution, which is critical for efficient downstream separation. Controlled granularity enhances separation accuracy and reduces metal residue in non-metal outputs.
Effective Dust & Emission Control
Equipped with pulse-jet dust collectors and negative-pressure systems to capture fine particles generated during crushing and grinding. The closed-loop design reduces airborne contamination and ensures compliance with environmental and workplace safety standards.
Wide Compatibility for E-Waste Boards
Suitable for processing computer motherboards, telecom boards, industrial control boards, and mixed electronic scrap. Modular configurations allow adjustment based on board thickness, component density, and production capacity requirements.
Modular & Scalable System Design
From small-scale pilot lines to high-capacity industrial plants, the modular structure supports flexible expansion. Independent functional units simplify maintenance, reduce downtime, and provide long-term operational reliability for growing recycling operations.

Frequently Asked Questions
What is the material ratio after removing tin from waste PCBs?
After de-soldering, the typical ratio in a pcb recycling machine is about 20% PCB boards and 80% electronic components, depending on the board type.
What is the annual maintenance cost of a PCB recycling system?
The annual maintenance cost of a waste pcb recycling machine is usually around 5%–10% of the total equipment cost, depending on capacity and operating conditions.
Does a PCB recycling machine produce pollution?
A pcb recycling machine does not produce liquid or hazardous emissions, but it may generate dust, which is controlled by a dust collection system.
What is the noise level of a PCB recycling system?
The noise of a waste pcb recycling machine can reach around 100 dB, mainly from the hammer crusher. It is recommended to install a soundproof enclosure around the crushing area.
