With global thermal drying energy demand projected to hit 8.3 EJ by 2030 (IEA), our rotary dryers offer a paradigm shift in processing sludge, sand, and coal slurry.
Case in Point: Coal Dehydration Breakthrough in Indonesia
Client: Kalimantan Energy Solutions
Challenge:
Reducing 38% moisture coal slurry to ≤12% for transport
Previous dryer caused 8% combustible dust emissions
42% gas consumption exceeding budget
Solution:
Custom-designed GD-2500 Triple-Pass Dryer with:
✓ Counterflow Air Recycling: Preheats incoming air with exhaust (65°C→210°C)
✓ Anti-Dust Flight Design: Material cascading pattern cuts particulate release by 91%
✓ Moisture Gradient Control: Zone-specific temperatures prevent over-drying
Performance Metrics:
Throughput increased from 12→18 tons/hour
Gas costs reduced to 3.8/ton(from6.5/ton)
Achieved MSHA-compliant dust levels
Engineering Principles at Work
Thermal Efficiency
Our dryers recover 72% of latent heat through:
Exhaust gas condensation
Insulated outer shells (0.35 W/m²K rating)
Material-Specific Geometry
Coal flights differ from sand/sludge configurations:
Deeper flights for sticky materials
Angled flights for free-flowing sands
Safety by Design
Explosion-proof zones and oxygen monitoring comply with ATEX Directive 2014/34/EU.
Final Note
Drying technology shouldn’t force trade-offs between efficiency and safety. Our systems demonstrate that industrial-scale dehydration can be both economically and environmentally responsible.
