Cameroon-Specific Adaptations

Climate & Infrastructure

1. High Humidity (Douala Region)
   • Enclosed electrical panels with dehumidifiers
   • Corrosion-resistant paint (ISO 12944 C5-M standard)
2. Power Instability
   • 400kVA diesel generator backup
   • Soft starters for all major motors
3. Remote Locations
   • Containerized control room
   • On-site spare parts inventory (minimum 2-week supply)

Material Challenges

• Basalt Characteristics:
  • High abrasiveness → Tungsten carbide tips for wear parts
  • Columnar jointing → Pre-screening with grizzly
  • High density (3.0g/cm³) → Heavy-duty conveyors
• Dust Control:
  • Dry fog system at transfer points
  • 500m² fabric filter dust collector

Expected Performance

Maintenance Plan

Daily:

• Check jaw crusher hydraulic tension rods
• Monitor cone crusher lube oil temperature (<60°C)
• Clean screen panels with air lance

Weekly:

• Measure jaw plate wear (replace at 70% wear)
• Inspect cone crusher mantle/bowl liner
• Grease all vibratory bearings (EP-2 lithium grease)

Monthly:

• Rotate screen panels (extend service life)
• Test emergency stop systems
• Calibration of weighing systems

Economic Considerations

Capital Investment:

• Equipment Package: $450,000-$500,000
• Civil Works: $80,000 (reinforced foundations)
• Electrical: $60,000 (including generator)

Operational Costs:

• Wear Parts: $0.25-0.30/ton (basalt abrasiveness)
• Power: $0.28/kWh (Cameroon average)
• Labor: 4 operators per shift

ROI Calculation:

• Current Yaoundé Market Prices:
  • Road Base: $18/ton
  • Concrete Agg: $22/ton
• Payback Period: 22-28 months

Key Advantages for Cameroon

1. Material Suitability:
   • Jaw crusher‘s deep chamber handles columnar basalt
   • PYB1750‘s coarse cavity ideal for hard rock
   • 3YK2160’s high G-force screening (4.5-5.0G)
2. Infrastructure Adaptations:
   • Modular design for quick relocation
   • Low-tech maintenance requirements
   • 20ft containerized spare parts storage
3. Economic Benefits:
   • Reduces import of construction materials
   • Creates local employment (30+ jobs)
   • Supports PNDP road projects
