Jaw Crusher For 50TPH Granite Processing in Tanzania

Introduction
Granite mining and processing are vital to Tanzania‘s construction and infrastructure development. However, processing hard granite requires durable equipment capable of handling high production demands. This case study explores how a customized jaw crusher solution successfully achieved 50TPH granite processing for a Tanzanian quarry operator, ensuring productivity, cost-efficiency, and long-term reliability.

Client Background

A mid-sized quarry operator in Mwanza, Tanzania, specializing in granite aggregate production for local road construction and building projects. The client needed to upgrade their crushing system to meet rising demand while maintaining a target output of 50 tons per hour (TPH).

Key Challenges:

1. Processing hard granite with compressive strength over 200 MPa
2. Minimizing downtime in harsh operating conditions
3. Achieving consistent 50TPH output with energy efficiency
4. Limited budget for equipment maintenance

Solution: Customized Jaw Crusher for Granite

After analyzing the granite properties and site conditions, we recommended a PE-400×600 jaw crusher as the primary crushing unit, paired with auxiliary equipment for a complete 50TPH granite processing line.

Equipment Specifications:

• Jaw Crusher Model: PE-400×600
• Feed Opening: 400×600 mm
• Max Feed Size: 340 mm
• Output Size: 40-100 mm (adjustable)
• Capacity: 50-80 TPH (optimized for 50TPH granite)
• Power: 30 kW electric motor

Advantages for Tanzanian Operations:
✅ Robust Construction: High manganese steel jaw plates withstand abrasive granite.
✅ Energy Efficiency: 20% lower power consumption vs. older models.
✅ Easy Maintenance: Modular design simplifies part replacement.
✅ Dust Control: Integrated water spray system complies with Tanzanian environmental regulations.

Implementation Process

1. Site Preparation
   • Cleared and leveled the crushing zone near the granite deposit.
   • Installed a 380V power supply for stable operations.
2. Installation & Commissioning
   • Jaw crusher mounted on a steel-framed base for vibration reduction.
   • Integrated with vibrating feeder (GZD750×2500) and belt conveyors.
3. Performance Testing
   • Achieved 52 TPH output with 35 mm discharge size.
   • Reduced oversized rocks by 90% compared to the previous hammer crusher.
4. Operator Training
   • Conducted on-site training for 8 technicians on safety protocols and routine maintenance.

Results & Benefits

After 6 months of operation:

• Production Output: Consistently reached 50-55 TPH, exceeding client expectations.
• Cost Savings:
  • 15% reduction in energy costs.
  • 40% fewer unplanned downtimes.
• Maintenance: Jaw plate lifespan extended to 6 months (vs. 3 months with previous equipment).

Client Feedback:
“The jaw crusher’s durability in Tanzania’s climate has been impressive. We’ve doubled our aggregate supply to local contractors without increasing labor costs.” – Site Manager, Mwanza Quarry

Why Choose a Jaw Crusher for Tanzanian Granite?

1. High Reduction Ratio: Ideal for primary crushing of hard granite (6:1 to 8:1).
2. Adaptability: Handles variable feed sizes common in African quarries.
3. Low Operating Costs: Minimal replacement parts and 2 hours/day maintenance.
