PCB Crushing and Metal Sorting Line
A PCB crushing and metal sorting production line is essentially a complete set of equipment designed for the physical crushing and efficient separation of metals from waste printed circuit boards. Its core function is to convert mixed electronic waste into reusable metal resources (such as copper and aluminium), thereby increasing recycling value whilst reducing the costs of manual dismantling and environmental impact.
PCB Crushing and Metal Sorting Line
Line Configuration: Synergistic Design from Crushing to Sorting
This PCB recycling production line typically comprises a feeding system, primary crusher, secondary grinding equipment, conveying system, and multi-stage sorting modules. Waste circuit boards can enter the crushing stage directly without complex disassembly; through two-stage grinding, the material is progressively reduced to a particle size suitable for sorting. The entire line employs a closed-loop conveying design, effectively minimising dust leakage and making it suitable for continuous operation.
In actual on-site operation at client facilities, the advantages of this integrated structure are evident: it reduces manual intervention, enhances processing efficiency, and ensures a stable flow of material between different stages, thereby preventing blockages or uneven sorting.
Core Equipment: Crushing and Metal Sorting System
The key to the equipment’s performance lies in the coordination between the crushing and sorting systems. The crushing section typically employs a high-strength cutting tool structure capable of processing circuit boards of varying thicknesses and materials to ensure a consistent output, whilst the sorting stage combines air classification and electrostatic separation technologies to effectively distinguish between metallic and non-metallic materials.
Specifically, air classification is primarily used for the initial separation of lightweight impurities, whilst electrostatic separation is employed for the precise purification of metals within fine particles, ensuring the recovery rate of metals such as copper powder. Through a combination of multi-stage sorting, the entire system can achieve a high-purity metal output without the need for chemical treatment.
On-site Operational Performance: Stability and Adaptability
Based on feedback from customer sites, this type of PCB recycling equipment demonstrates outstanding stability during continuous operation. The equipment supports the processing of various types of low-value circuit boards, such as those from household appliances and telecommunications, which can enter the production process directly without the need for pre-sorting.
Furthermore, the entire line is designed with a degree of flexibility. SUNY GROUP can adjust configurations to meet the production capacity requirements of different clients, for example, by increasing the number of crushing stages or optimising the sorting modules, to suit e-waste processing projects of varying scales. This customisability makes the equipment easier to implement in practical recycling scenarios.
