another 100tph river stone crusher plant set up in Tacloban, Philippines

Here’s a comprehensive 100tph river stone crushing plant solution specifically designed for Tacloban, Philippines, incorporating your specified equipment while addressing local environmental and operational challenges:

Plant Configuration & Process Flow

1. Primary Crushing Stage

• PE-600×900 Jaw Crusher
  • Feed Opening: 600×900mm (24×35 inches)
  • Max Feed Size: ≤500mm (20 inches)
  • Discharge Setting: 65-160mm (adjustable)
  • Capacity: 50-100tph (matches target)
  • Motor Power: 55-75kW
  • Key Features:
    • Deep crushing chamber handles rounded river stones
    • Manganese steel jaw plates resist silica abrasion
    • Simple mechanical structure for easy maintenance

Pre-crushing Setup:

• Grizzly feeder with 80mm spacing to remove oversized boulders
• Water spray system to reduce dust from moist feed material

2. Secondary Crushing Stage

• PSGB0917 Symons Cone Crusher
  • Type: Standard coarse crushing
  • Feed Size: ≤150mm (from jaw crusher)
  • Discharge Setting: 16-38mm (adjustable)
  • Capacity: 45-91tph
  • Motor Power: 75kW
  • Key Advantages:
    • Interparticle crushing improves particle shape
    • Spring protection against tramp metal
    • Suitable for high-moisture materials

Optimization Tip:

• Install metal detector before cone crusher to protect from rebar/steel debris

3. Screening & Grading

• 3YK1548 Vibrating Screen
  • Screen Size: 1500×4800mm (3 decks)
  • Capacity: 100-150tph
  • Screening Media:
    • Top deck: 40mm rubber panels (for longevity)
    • Middle deck: 20mm woven wire
    • Bottom deck: 5mm polyurethane for sand
  • Slope: 15-20° for better material flow

Closed Circuit Design:

• Oversize (>40mm) returns to cone crusher via conveyor
• Middle product (20-40mm) for concrete aggregate
• Fine product (5-20mm) for road base
• Sand fraction (0-5mm) to stockpile

Tacloban-Specific Adaptations

Expected Performance Metrics

Maintenance Plan

Daily:

• Check jaw crusher toggle plate tension
• Inspect cone crusher lubrication system
• Clean screen meshes with air guns

Weekly:

• Measure jaw plate wear (flip at 60% wear)
• Check Symons cone bushings
• Grease all vibratory bearings

Monthly:

• Rotate screen media (extend lifespan)
• Replace conveyor skirting
• Test emergency stop systems

Typhoon Preparedness:

1. Pre-storm:
   • Secure loose components
   • Cover electrical equipment
   • Fuel backup generator
2. Post-storm:
   • Drain water from bearings
   • Check motor insulation resistance
   • Inspect structural integrity

Economic Considerations

Capital Costs:

• Equipment package: $280,000-$320,000
• Civil works: $50,000 (foundations, drainage)
• Electrical: $30,000 (including backup generator)

Operational Costs:

• Wear parts: $0.15-0.20/ton
• Power: $0.18/kWh (Mindanao grid rate)
• Labor: 3 operators/shift

Return on Investment:

• Current Tacloban market prices:
  • Aggregate: $12-15/ton
  • M-sand: $18-22/ton
• Payback period: 18-24 months

Why This Configuration Works

1. Material Suitability:
   • Jaw crusher handles irregular river stones
   • Symons cone produces well-graded aggregate
   • Screen effectively separates sand fraction
2. Climate Adaptation:
   • Corrosion-resistant materials
   • Flood-proof design
   • Moisture-tolerant crushing process
3. Market Demand:
   • Supplies reconstruction projects
   • Provides alternative to banned river sand
   • Meets DPWH standards for infrastructure
