PCB Shredders and Recycling Machines

The PCB circuit board recycling production line developed by SUNY GROUP centers on the synergistic operation of multi-stage crushing and precision sorting equipment, achieving the effective separation of metals from resin powder. This enhances resource recovery efficiency and reduces processing costs.

Crushing and Pulverizing Equipment Configuration

The first step in PCB recycling is size reduction. This typically involves using a dual-shaft shredder to crush whole circuit boards into smaller fragments coarsely. The material then proceeds to a hammer mill or blade pulverizer for secondary refinement, reducing it to a particle size suitable for sorting. To ensure optimal subsequent sorting results, the system also incorporates grinding equipment to further pulverize the mixture into a uniform fine powder, thereby maximizing the degree of dissociation between metallic and non-metallic components. The entire crushing stage emphasizes continuous feeding and stable discharge to ensure the smooth operation of the production line.

Core Equipment for Sorting and Purification

Once pulverization is complete, the critical task is to achieve the effective separation of different materials. First, an airflow sorting system is employed to preliminarily separate lightweight resin powder from heavier metal particles based on density differences. Subsequently, an electrostatic separator is utilized to perform a fine separation between metallic and non-metallic components—a crucial step in enhancing the purity of the recovered materials. Some systems are also equipped with magnetic separators to remove ferrous impurities. Through this combination of multi-stage sorting processes, the final output consists of high-purity metal powder and reusable non-metallic powder.

Auxiliary Systems and Operational Features

To ensure stable equipment operation, the PCB recycling line is typically outfitted with a comprehensive dust removal system that effectively controls dust dispersion and improves the working environment. Furthermore, the entire line utilizes PLC-based automatic control to facilitate the coordinated operation and parameter adjustment of individual machines, thereby minimizing the need for manual intervention. The modular design allows the production line to be flexibly configured according to processing scale, making it suitable for recycling scenarios with varying capacity requirements.
