New three-drum rotary dryer for drying silica sand

The Triple-Drum Rotary Dryer is an advanced industrial drying system designed for high-efficiency moisture removal from bulk materials such as sand, slag, clay, minerals, and biomass. Its unique three-cylinder structure enhances heat utilization, reduces energy consumption, and ensures uniform drying.

Key Features
1. High Thermal Efficiency
– Three concentric cylinders maximize heat exchange, reducing fuel consumption by 20-30% compared to single-drum dryers.
– Inner and outer drums optimize hot air circulation, minimizing heat loss.

2. Compact & Space-Saving
– The nested drum design reduces the machine’s length by 40-50%, making it ideal for limited-space installations.

3. Uniform Drying
– Material flows through multiple layers, ensuring even heat distribution and preventing over-drying or clumping.

4. Low Maintenance & Robust Construction
– Made from wear-resistant steel with thermal insulation to withstand high temperatures (up to 700°C).
– Reduced dust emissions with optional bag filters or cyclones.

5. Wide Material Adaptability
– Suitable for granular, powdery, and high-moisture materials (e.g., sand, coal, sawdust, ore, sludge).

Technical Specifications
– Capacity: 5–200 t/h (customizable)
– Moisture Reduction: From 30-40% to <1%(adjustable)
– Heat Source: Coal, gas, biomass, or electric heating
– Temperature Range: 150–700°C
– Control System: Manual or automated (PLC-based)

Applications
Construction: Sand, gravel, clay, gypsum
Mining & Metallurgy: Ore, mineral powder, slag
Agriculture: Biomass, wood chips, feed
Chemical Industry: Fertilizer, salts, industrial sludge

Advantages Over Single-Drum Dryers
Lower fuel consumption(up to 30% energy savings)
Smaller footprint (suitable for modular setups)
Higher drying efficiency (reduced material sticking & clogging)
Longer service life (reinforced structure & corrosion protection)
