Core Technical Advantages

1. Energy-efficient Process

Three-stage Spiral Heat Exchange: Combined co-current/counter-current drying achieves 88% thermal efficiency with 35% lower energy consumption.

Waste Heat Cascade Utilization: Integrated flue gas boiler saves over 400 tons of coal annually.

2. Smart Control System

PLC automation supports real-time parameter adjustment and 99% fault prediction accuracy.

AI algorithm enables unattended operation with dynamic optimization.

3. Advanced Environmental Compliance

Four-stage Dust Removal: Emissions ≤5mg/m³ via cyclone → multi-tube → baghouse → wet scrubber.

Optional SCR denitrification system reduces NOx to <30mg/m³.

4. Wear-resistant Design

High-chromium cast iron lining extends service life to 10+ years.

Spiral lifting device reduces material retention and wear by 60%.
