Rotary Dryer
Capacity: 1-100TPH
Feeding Size: 0-50mm
Moisture content: 1-10%(0-50 mm)
Handling Materials: Concentrate, ammonium sulfate, PVC powder, feed, organic fertilizer, etc.
Rotary dryer reduces moisture from 15–40% to 1–10% in materials (0–50mm) like ores, fertilizers, and biomass, handling 1–100t/h. Heated by gas, coal, or steam (200–800°C), it suits high-volume drying but avoids heat-sensitive or ultrafine powders.
Advantages
01.
High Capacity
Handles 1–100t/h throughput for diverse materials (0–50mm), from ores to biomass, with customizable drum lengths for extended drying time.
02.
Fuel Flexibility
Supports gas, coal, oil, or steam heating (200–800°C), adapting to local energy availability and cost requirements.
03.
Robust Construction
Carbon steel or stainless steel drums with lifters endure abrasive materials (iron ore) for 10+ years of service.
04.
Easy Control
Adjustable rotation speed (2–8 RPM) and temperature optimize moisture reduction (to 1–10%) for different materials.
How Does A Rotary Dryer Work
1. Material Feeding: Wet feedstock (15–40% moisture, 0–50mm) enters the rotating drum via a conveyor, distributed evenly by internal lifters/flights.
2. Heat Transfer: Hot air (200–800°C) flows counter-currently, evaporating moisture as the drum rotates (2–8 RPM), maximizing contact time.
3. Drying Progression: Lifters cascade materials through the hot air stream, ensuring uniform drying while preventing clumping or overheating.
4. Product Discharge: Dry product (1–10% moisture) exits the drum’s end, while exhaust gases pass through dust collectors (cyclones/bag filters).
