DC1500 Model Asphalt Mixing Plant

1. Batching System

• Variable frequency-controlled belt feeding ensures precise primary batching.

• Material breakage alarm + bridge-breaking device prevents material voids and blockages, enabling efficient and stable operation.

• Modular hard-geared reducer features compact structure, high transmission efficiency, low failure rate, and easy maintenance.

2. Dust Removal System

• German dust removal technology combines inertial separation and pulse bag filtration, achieving dust emissions <20 mg/Nm3 (environmentally compliant).

• Over-temperature protection: Dual safeguards – cold air valve auto-opens for high exhaust temperatures; burner auto-shuts down for critical overheating.

3. Drying System

• High-temperature-resistant scraper plates in the drum ensure uniform material distribution and efficient heat exchange, extending service life.

• Low-pressure atomization + mechanical-assisted fuel spray (adjustment ratio 1:10) supports multiple fuels (diesel, heavy oil, natural gas) with low noise.

• Four-wheel friction drive delivers high transmission efficiency and smooth operation.

4. Hot Aggregate Elevator System

• Double-row plate chain bucket elevator operates quietly and stably with extended durability.

• High-strength low-alloy steel buckets with wear-resistant edge strips and welded reinforcement ensure robustness and longevity.

5. Screening System

• Proprietary dual-shaft vibrating linear screen integrates vibration motors and eccentric shafts for high efficiency, rapid screen replacement, and maintenance-free bearings.

• Triple overflow protection:

  • Material level sensor for real-time monitoring

  • Overflow pipeline for automatic discharge

  • Oversize/off-spec aggregate channel for non-compliant materials

6. Weighing System

• Aggregate scale: Tension-type load cells with automatic splashing error correction; dual scales for large-tonnage units (±2.5% accuracy).

• Powder scale: Three-point tension load cells (±2% accuracy).

• Asphalt scale: Three-point tension load cells with secondary tracking (±2% accuracy).

7. Mixing Unit

• Dual horizontal-shaft mixer with high-strength Ni-Cr alloy liners and blades for extended durability.

• Linkage-flip discharge gate ensures rapid opening/closing without jamming.

• Insulated finished product silo maintains mix temperature (≤5℃ drop within 12h at 15–25℃ ambient).

8. Control System

• German SIEMENS PLC control cabinet supports automatic/semi-automatic/manual modes. Functions include:

  • Recipe input/storage

  • Dynamic error correction

  • Parameter adjustment

  • Calibration

  • Asphalt-aggregate ratio tracking

  • Fault diagnosis/alerts

  • Data reporting/printing

9. Installation & After-Sales

• Modular design simplifies installation, maintenance, and relocation.
