Optimizing Production with the Fintec 1107 Jaw Crusher in Aggregate Processing

The aggregate industry relies heavily on efficient crushing equipment to meet the growing demand for high-quality sand and gravel. Among the key players in this sector, the Fintec 1107 Jaw Crusher stands out for its robust design and adaptability in primary crushing applications. This machine, now part of ’s legacy, was engineered to handle hard rock, recycled concrete, and other abrasive materials, making it a staple in quarries and recycling plants.

Core Features & Production Calculation
The Fintec 1107’s production capacity hinges on several variables:

  • Feed size: Optimal performance is achieved with a maximum feed size of 700mm.
  • CSS (Closed Side Setting): Adjusting the CSS (range: 50–150mm) directly impacts output gradation and throughput.
  • Material hardness: Softer materials like limestone yield higher tonnage (~300 tph), while granite may reduce output by 20–30%.
  • Operational efficiency: Proper feeder speed, crusher RPM (220–260), and minimal downtime are critical.

    • A simplified production estimate can be derived using:
    \[ \text{Production (tph)} = \text{Theoretical Capacity} \times \text{Efficiency Factor (0.6–0.8)} \]
    For example, with a CSS of 100mm processing medium-hard rock:
    \[ 250 \, \text{tph} \times 0.7 = 175 \, \text{tph} \]

    Common FAQs
    1. How to minimize wear on jaw plates?
    Rotate or flip plates periodically; ensure proper feed distribution to avoid uneven wear.
    2. What causes frequent belt slippage?
    Check tension and alignment; worn or contaminated belts require replacement.
    3. How to troubleshoot low throughput?
    Verify CSS settings, feed gradation, and eliminate bottlenecks in upstream equipment.

    Case Study: Limestone Quarry Upgrade
    A Texas-based operator replaced an aging primary crusher with a Fintec 1107, achieving:

  • 25% higher uptime due to reduced blockages from the hydraulic CSS adjustment.
  • Consistent output of 200 tph for base material production, meeting DOT specifications.

By understanding the Fintec 1107’s operational parameters and maintaining proactive upkeep, aggregate producers can maximize ROI while ensuring reliable performance in demanding environments.
