300TPH Limestone Crusher Plant in Sri Lanka – Complete Setup & Performance Analysis

🔧 Plant Configuration & Key Equipment

1️⃣ Vibrating Feeder – GZT1256

• Capacity: 300-400 TPH (adjustable)
• Function: Ensures smooth, controlled feeding to the jaw crusher, preventing blockages.
• Advantage: Heavy-duty design for large limestone chunks.

2️⃣ Primary Crushing – PE-750×1060 Jaw Crusher

• Capacity: 110-320 TPH (depends on CSS setting)
• Max Feed Size: ≤ 630mm
• Output Size: 80-180mm (adjustable)
• Ideal for Limestone: High crushing force, low wear cost.

3️⃣ Secondary Crushing – PF-1320 Impact Crusher

• Capacity: 160-350 TPH
• Max Feed Size: ≤ 500mm (matches jaw crusher output)
• Output Size: ≤40mm (adjustable for finer crushing)
• Advantage: Produces cubical-shaped aggregates, ideal for concrete & asphalt.

4️⃣ Screening – 3 Sets of 3YK1848 Vibrating Screens (Triple-Deck)

• Screen Size: 1.8m × 4.8m (each)
• Total Screening Capacity: 300-350 TPH
• Output Sizes:
  • 0-5mm (Fine Sand) – For concrete & plastering
  • 5-15mm & 15-30mm (Gravel) – For construction & road base
  • 30-50mm (Coarse Aggregate) – For drainage & foundations
• Closed-Circuit Design: Oversized material (>50mm) recirculates to the impact crusher.

📊 Expected Performance & Output

✔ Throughput: Stable 300 TPH when optimized.
✔ Final Product Sizes:

• 0-5mm (Sand) – High demand for concrete & masonry.
• 5-15mm & 15-30mm (Gravel) – For asphalt & construction.
• 30-50mm (Coarse Aggregates) – For road base & large projects.
  ✔ Low Operating Cost: Impact crusher reduces recirculation load.

✅ Why This Setup Works for Sri Lanka’s Limestone?

✔ High Efficiency – Jaw + Impact combo maximizes crushing power.
✔ Precise Screening – Triple-deck screens ensure accurate grading.
✔ Scalable Production – 3 screens allow parallel processing for higher efficiency.
✔ Meets Local Demand – Produces all key aggregate sizes for roads, buildings, and infrastructure.

🔧 Maintenance & Optimization Tips

• Monitor Feed Size: Ensure limestone ≤ 600mm to avoid jaw crusher overload.
• Check Wear Parts: Regularly inspect jaw plates, impact blow bars, and screen meshes.
• Adjust Crusher Settings: Fine-tune CSS (Jaw) & rotor speed (Impact) for optimal output.
• Dust Control: Use water spray or bag filters to comply with environmental regulations.

🚀 Possible Upgrades (Future Expansion)

• Sand Washer – For cleaner, higher-value sand (if market demands).
• Tertiary Crusher (VSI Crusher) – For better-shaped sand production.
• Automation System – Remote monitoring & real-time adjustments.

🎯 Conclusion

our 300TPH limestone crusher plant in Sri Lanka is a high-performance, reliable setup designed to meet local construction needs efficiently. With proper operation, it will deliver consistent, high-quality aggregates for years.
