  • Extract ferrous metals (e.g., steel) from non-ferrous fractions. Tomra’s Finder Unit recovers stainless steel and copper wires from plastic waste .
• Centrifugal Dewatering Units:
  • Reduce moisture content to <5% for metal particles. Tomra’s water-ring dryer (1,000 kg/hour) costs $15,000–$30,000 .

2. Price Range by System Configuration

2.1 Small-Scale Systems (50–500 kg/hour)

• Lab/Pilot Lines:
  • For R&D or small businesses. Huaming Machinery’s lab system (5–20 kg/hour) costs $9,500–$10,000 .
• Mini Production Lines:
  • Handle clean enclosures. Hubei Ruifeng’s basic line (300 kg/hour) with pre-wash and drying: $2,600–$5,300 .

2.2 Industrial-Scale Systems (1–5 tonnes/hour)

• Standard Lines:
  • Process mixed enclosures. China Suppliers’ 19.88 万 RMB line (1,500 kg/hour) includes AI sorting and closed-loop washing: $27,600+ .
• Advanced Lines:
  • Include IoT monitoring and energy recovery. Tomra’s AUTOSORT™ with GAINnext™ (1–5 tonnes/hour): $130,000+ .

2.3 Specialized Systems

• Hazardous Waste Lines:
  • Handle contaminated enclosures (e.g., electronics with PCB residues). X 技术专利’s explosion-proof system with gas scrubbers: $50,000+ .
• High-Purity Recycling Lines:
  • Use nanobubble technology (e.g., Friesen’s ozone system) to produce 99.9% pure metal for automotive applications: $120,000+ .

3. Key Factors Influencing Prices

3.1 Material Contamination

• Clean Enclosures:
  • Lower processing costs ($15,000–$50,000 for a 300 kg/hour line) .
• Hazardous/Contaminated Materials:
  • Require advanced scrubbing and gas treatment (e.g., X 技术专利’s three-stage washing), increasing costs by 20–40% .

3.2 Automation and Energy Efficiency

• Manual Systems:
  • Lower upfront costs ($10,000–$30,000) but higher labor expenses .
• Fully Automated Lines:
  • Reduce energy use by 25% (e.g., MSS Cirrus® IoT system) but cost 20–40% more .

3.3 Brand and Quality

• Premium Brands (e.g., Tomra, Coperion):
  • Offer 5–10 year warranties and CE/ISO certifications, with prices 20–30% higher .
• Chinese Suppliers (e.g., Purui Machinery):
  • Cost-effective solutions ($2,000–$50,000) with shorter lead times .

4. Cost-Benefit Analysis

4.1 Financial Returns

• Material Recovery:
  • Clean aluminum pellets sell for $1,200–$1,500/tonne, while high-purity steel fetches $800–$1,000/tonne .
  • Example: A 300 kg/hour line processing metal enclosures generates $30,000–$45,000 monthly revenue at full capacity .
• Energy Savings:
  • Hybrid systems (e.g., Tomra’s PET Line) save $5,000–$10,000 annually in electricity costs .

4.2 ROI Timeline

• Small-Scale Lines:
  • Pay off in 1–2 years through reduced disposal costs and material sales .
• Industrial Lines:
  • Achieve ROI in 3–5 years due to higher throughput and premium material prices .

5. Choosing the Right Equipment

1. Material Compatibility:
   • Metal Enclosures: Opt for lines with AI sorting (e.g., Tomra’s X-TRACT™) .
