350 TPH Granite Crushing Plant in Nigeria

Customer Background

Our client is a leading construction and mining company in Nigeria specializing in granite quarrying and aggregate production. With increasing infrastructure demands, they needed a high-capacity, efficient, and durable granite crushing plant to meet the growing market needs.

Project Overview

• Location: Nigeria
• Material: Granite
• Required Output: 300-350 tons per hour
• Final Product: 0-5mm, 5-10mm, 10-20mm, and 20-40mm aggregates for construction

Challenges

1. High Hardness of Granite – Requires robust and wear-resistant crushing machinery.
2. High Production Demand – Needs a stable and large-capacity crushing plant.
3. Strict Output Gradation – Requires precise control over particle sizes.
4. Cost-Effective Operation – Must minimize downtime, maintenance, and power consumption.

Solution by Liming Heavy Industry

To meet these challenges, we designed a complete granite crushing and screening solution using our high-performance equipment:

1. Primary Crushing – PE1200×1500 Jaw Crusher

• Role: Coarse crushing of large granite blocks (up to 1000mm) into smaller rocks.
• Advantages:
  • High crushing ratio and strong structure for granite processing.
  • Large feed opening and deep crushing chamber for improved throughput.
  • Energy-efficient operation reduces operational costs.

2. Secondary Crushing – HST315 Hydraulic Cone Crusher

• Role: Further crushing of coarse granite into medium-sized aggregates (10-40mm).
• Advantages:
  • Advanced hydraulic system for stable output and optimal particle shape.
  • Automatic overload protection to prevent damage from uncrushable materials.
  • High wear resistance with manganese steel liners.

3. Sand Making – VSI6X1150 Impact Crusher

• Role: Produces high-quality 0-5mm sand for construction applications.
• Advantages:
  • Deep rotor design maximizes sand yield and shapes product into cubic particles.
  • Low energy consumption and high efficiency for sustainable operations.
  • Reduced wear with advanced material flow design.

4. Screening – YKN2460 Vibrating Screen

• Role: Classifies crushed materials into precise size fractions.
• Advantages:
  • High screening efficiency with customizable meshes.
  • Large processing capacity for seamless integration into the production line.
  • Durable construction with minimal maintenance requirements.

5. Supporting Equipment

• Belt conveyors (B1200, B1000) for smooth material transfer.
• Dust control system for environmental compliance.

Technical Highlights

• High Automation Control – PLC system ensures smooth operation with real-time monitoring.
• Energy-Efficient Design – Optimized equipment layout reduces power consumption.
• Durability & Reliability – Premium wear-resistant materials extend machine lifespan.
• Easy Maintenance – Modular design facilitates quick component replacement.

Project Results

• Production Capacity Achieved: 350 TPH (exceeding initial requirements).
• Final Product Quality: Well-graded 0-5mm sand + multiple aggregate sizes.
• Reduced Downtime: Reliable operation with minimal mechanical failures.
• Cost Savings: Lower energy and maintenance expenses compared to competitors.
