The Shuliy SL Series is specifically engineered for the physical separation of metals and non-metals from scrap electronics. Operating as a heavy-duty motherboard recycling machine, the system processes copper-clad laminates (CCL), rigid printed circuit boards, and electronic offcuts.

The primary goal of waste circuit board recycling is to cleanly fracture the composite structures without chemical agents or water discharge, effectively isolating conductive metal powders from resin substrates.

The system adopts a dry mechanical process to handle e-waste. By integrating multiple stages into a continuous sequence, this PCB crusher and separator ensures precise material reduction and classification.

1. Primary and Secondary Size Reduction Raw material is fed into the Shredder for coarse breaking. The output is conveyed directly to the Hammer Crusher, where high-impact forces reduce the boards into smaller fragments suitable for grinding.
2. Temperature-Controlled Milling and Screening The fragments enter the Water-cooled Mill. Milling generates heat, which can melt resin and lower separation efficiency. The integrated water circulation jacket maintains optimal temperatures inside and outside the grinding chamber. The milled powder then passes through a Rotary Screening Machine to ensure uniform particle size.
3. Gravity and Electrostatic Separation The mixed powder is directed into the Air Separator, which uses specific gravity differences to extract the bulk of the metal powder. The remaining non-metallic fraction, which still contains trace amounts of micro-metals, is processed by the Electrostatic sorting machine. This high-voltage sorting forces the final separation of pure metal powder and resin powder.

Technical Specifications of the PCB Recycling Machine

The Shuliy SL Series is scaled in four standard models to meet different plant capacities. All models provide consistent metal recovery rates (≧98%) and dust collection efficiency (≧99%), differing primarily in motor power and throughput.

Key Engineering Features of the Printed Circuit Board Recycling Plant

A functional E-waste PCB separator must balance throughput with environmental compliance and operational safety.

Intelligent Load Control The entire system operates on a central PLC architecture featuring an intuitive HMI touch screen. This infrastructure ensures synchronized feeding rates across the entire line, preventing bottlenecks at the crusher or separator inputs and minimizing operator intervention.

Integrated Dust Management Crushing circuit boards generates a substantial amount of fiberglass and resin dust. The Shuliy line utilizes a negative pressure feeding network coupled with a Pulse dust removal system. This infrastructure captures airborne particulates directly from the processing chambers, protecting the working environment and minimizing material loss.

Acoustic Treatment Industrial shredding and milling generate high decibel levels. The crushing modules in the SL Series undergo structural noise reduction treatments, including isolated mounting and reinforced enclosures, reducing vibration and airborne noise within the facility.
