Kue-Ken Jaw Crusher Model 12 x 24 Capacity Chart: A Comprehensive Technical Review

Industry Background

Jaw crushers have been fundamental to mineral processing and aggregate production for over a century. Among the notable manufacturers, Kue-Ken stands out for its robust engineering and reliable crushing solutions. The Kue-Ken Model 12 x 24 jaw crusher represents a mid-range unit designed for primary crushing applications, balancing throughput capacity with operational efficiency. Understanding its capacity chart is crucial for engineers, plant managers, and procurement specialists seeking optimal performance in mining, quarrying, and recycling operations.

Core Specifications & Design Features

The Kue-Ken Model 12 x 24 refers to a jaw crusher with a 12-inch (305 mm) feed opening and 24-inch (610 mm) jaw width. Key design attributes include:

  • Crushing Mechanism: Single-toggle design with deep crushing chambers for high reduction ratios.
  • Drive System: Typically powered by electric motors ranging from 30 to 50 HP, depending on configuration.
  • Construction: Heavy-duty cast steel frame with replaceable manganese jaw plates for extended wear life.
  • Adjustability: Hydraulic or mechanical toggle adjustment for precise control of discharge settings.

    • Capacity Chart Analysis

    Capacity charts provide estimated throughput rates under varying conditions (e.g., feed size, closed-side setting, material hardness). Below is a generalized capacity range for the Kue-Ken 12 x 24:

    | Closed-Side Setting (CSS) | Feed Size | Hard Material (TPH) | Medium Material (TPH) | Soft Material (TPH) |
    |—————————|———–|———————|———————–|———————|
    | 1″ (25 mm) | ≤6″ (150 mm)| 15–25 | 30–40 | 45–60 |
    | 2″ (50 mm) | ≤8″ (200 mm)| 25–35 | 40–55 | 60–80 |
    | 3″ (75 mm) | ≤10″ (250 mm)| 35–50 | 55–75 | 80–100 |

    Notes:

  • Hard materials: Granite, basalt (>200 MPa compressive strength).
  • Medium materials: Limestone, sandstone (~100–200 MPa).
  • Soft materials: Coal, gypsum (<100 MPa).
  • Actual output may vary based on moisture content, feed gradation, and crusher condition.

    • Market Applications & Operational Considerations

    Primary Use Cases

    1. Aggregate Production: Crushing run-of-mine rock to produce base materials for road construction.
    2. Mining Pre-Crushing: Reducing large ore fragments before secondary grinding circuits.
    3. Demolition Recycling: Processing concrete rubble into reusable aggregates.

    Performance Optimization Tips

  • Maintain consistent feed distribution to avoid uneven jaw wear.
  • Monitor CSS regularly—overly wide settings reduce particle shape quality.
  • Pair with vibrating grizzly feeders to remove fines before crushing (“scalping”).

    • Frequently Asked Questions (FAQ)

    Q1: What is the maximum recommended feed size?
    A: The crusher can handle up to ~80% of the gape width (~9–10″), but optimal efficiency occurs at ≤6″ feeds for finer CSS adjustments.

    Q2: How often should jaw plates be replaced?
    A: Lifespan depends on abrasiveness; manganese jaws typically last 6–18 months in abrasive conditions with regular rotation/reversal practices.

    Q3: Can this model handle wet or sticky materials?
    A: Limited effectiveness—clay-rich or high-moisture feeds may cause chamber clogging; pre-screening is advised.

    Engineering Case Example

    A quarry in Texas deployed two Kue-Ken 12 x 24 units for limestone processing:

  • Configuration: CSS set at 2″, feeding blasted limestone (~8″ top size). Motorized belt feeder ensured steady supply without bridging issues.
  • Output Achieved: Sustained 45 TPH (~500 tons/shift), producing well-graded ASTM 57 stone with <10% oversize—eliminating secondary crushing needs.

This setup reduced downtime by 20% compared to older double-toggle crushers due to simplified maintenance access inherent in Kue-Ken’s design.

Conclusion

The Kue-Ken Model 12 x 24 remains a versatile choice for mid-capacity crushing tasks when paired with proper operational protocols and realistic expectations derived from its capacity chart parameters ensuring long-term reliability across diverse industries demands careful attention toward maintenance schedules alongside material-specific calibration efforts maximizing return-on-investment potential significantly over time span deployments typical within modern aggregate sectors globally today
