200-300 kg/h Heavy-Duty PCB Recycling Lines PCB Shredder-Crusher Machine

For efficient recovery of valuable metals from e-waste, this line centers on a dual-shaft shredder as the primary stage. It aggressively shatters whole PCBs – breaking down composite fiberglass, resin, and embedded metals – into controlled fragments. This critical size reduction enables downstream milling and separation while liberating metals. Integrated dust suppression ensures environmentally compliant operation at 200-300 kg/h throughput, establishing the shredder as the foundational process for PCB resource recovery.

The Role of PCB Shredder-Crusher in PCB Recycling Process

PCB boards are typically composed of composite materials such as fiberglass, resin, and copper foil, featuring a hard structure with combined metal and non-metal components. The PCB shredder-crusher machine (or PCB board shredder) uses powerful rotating single-shaft blades to shear, squeeze, and tear the PCB boards, breaking them into smaller fragments (usually ranging from several centimeters to tens of centimeters). This step lays the foundation for subsequent fine processing (e.g., pulverization and sorting).

During the shredding process, the metal (e.g., copper foil) and non-metal substrate (fiberglass, resin) in PCB boards are preliminarily separated due to their different physical properties (hardness and ductility). Part of the metal debris falls off from the substrate, improving the efficiency of subsequent metal recovery.

Applications of PCB Shredder-Crusher Machine in PCB Recycling

1. Industrial-grade Preprocessing of PCB Waste

Application Scenarios: Electronic waste recycling plants, waste treatment workshops of PCB manufacturers.

Processing Objects: Waste circuit boards, trimmings, and PCB components from scrapped electronic devices (e.g., computer motherboards, mobile phone circuit boards).

Process Positioning: As the first step in the recycling process, it connects the “waste collection” and “fine crushing” stages.

2. Large-scale Recycling Production Lines

In automated recycling lines, the PCB shredder-crusher machine is usually linked with subsequent equipment (e.g., pulverizers, eddy current separators, electrostatic separators):

Shredded PCB fragments are conveyed to a pulverizer for further crushing into fine powder.

The fine powder is separated by sorting equipment into metal (copper, aluminum, etc.) and non-metal powders. The metal can be remelted for reuse, while the non-metal powders can be used as fillers or building materials.

Key Advantages of PCB Shredding-Crushing

1.High-Efficiency Fine Crushing

Processes PCB into 2-5 mm particles via high-speed rotation (800-1200 rpm), dissociating copper foil from substrates with ≥95% purity.

Suits thin PCB, flexible boards (FPC), and small electronic waste, avoiding jams from embedded components.

2.Low Energy & Maintenance Costs

Consumes 15-25 kW/h (30%-50% less than dual-shaft models), ideal for small-mid enterprises (daily capacity <10 tons).

Simple single-rotor design reduces maintenance by 50% and parts costs by 40%.

3.Flexible Material Handling

Resists (entanglement) when processing FPC, outperforming dual-shaft machines in flexible material adaptability.

Processes mixed e-waste (PCB + plastics + wires) without pre-sorting, shredding plastics into 5-10 mm pieces.

4.Precise Particle Control

90% of particles fall within 2-5 mm, directly feeding electrostatic separators for ≥98% copper recovery.

5.Environmental & Circular Benefits

Enclosed chamber reduces dust emission by 60%, meeting environmental standards.

Non-metal powder is recycled as construction fillers (enhances concrete strength by 8%-10%) or plastic additives.

6.Compact Design & Versatility

30% smaller than dual-shaft systems, suitable for mobile recycling units or space-constrained sites.

Adjustable speed (500-1200 rpm) adapts to ceramic PCB(low speed) and standard FR-4 boards (high speed).
