Henan Terbaik’s Double-Drum Dryer is an advanced, energy-efficient solution for drying granular materials in industries like cement, chemicals, and metallurgy. Its compact design and innovative heat exchange system ensure maximum efficiency and cost savings.
The Double-Drum Dryer is a direct rotary drying machine comprising an inner drum, an outer drum, support rollers, riding rings, a drive mechanism, and feed/inlet and discharge/outlet sealing devices. It is specifically designed for drying granular materials within specific moisture and particle size ranges. Widely used in industries such as dry mortar, casting, cement, and chemicals, the double-drum dryer can achieve post-drying moisture levels as low as 0.5%-1%. Unlike triple-drum dryers, it allows for easier replacement of lifting plates. For special high-temperature drying applications, the inner drum and lifting plates near the inlet can be made of heat-resistant steel.
1. High Thermal Efficiency: The dryer’s heat efficiency is over 50% higher than traditional single-drum dryers, leading to significant coal savings.
2. Efficient Heat Exchange:
Inner drum: Combines radiation, convection, and conduction.
Outer drum: Primarily conduction and convection.
3. Compact Design:
The overall length is about 40% shorter than single-drum dryers, reducing plant space requirements and construction costs.
Ideal for retrofitting existing plants.
4. Versatile Application: Suitable for drying materials like clay, coal, slag, iron powder, and bulk chemical raw materials.
5. Simplified Structure:
Horizontal layout with roller support eliminates the need for large gear mechanisms.
Roller transmission ensures ease of installation, operation, and higher reliability.
6. Improved Energy Efficiency:
External insulation provided by the outer drum reduces heat loss by over 30%.
Enhances working conditions by maintaining low external surface temperatures.
7. Advanced Lifting Plate Design:
Combines angular and zigzag designs for optimal heat exchange and reduced "wind tunnel" effects inside the drum.
8. Variable Speed Control:
Adjustable drum speed using frequency control ensures the dryer adapts to various moisture and production demands.
9. Automated Temperature Monitoring: Facilitates ease of operation with precise control of drying conditions.

Convenient transportation, crawler walking, no damage to the road, equipped with multi-functional accessories, Drived by oil and electricity.
The whole crushing plant adopts all-wheel drive to realize rotating direction in place, with perfect protection function, especially suitable for narrow and complex site.
The crawler crushing plant could be optional for jaw crusher, impatct crusher, cone crusher, VSI crusher etc.
It can work uphill to meet the crushing requirements of mining, hydropower station, coal mine and other projects.
The double-drum dryer is ideal for drying granular materials such as:
Yellow sand for dry mortar production.
Casting sand in various specifications.
Blast furnace slag in cement and building material industries.
Fine clay and non-reactive, heat-resistant small-particle materials in the chemical industry.
Key features include:
1. Material Input: Granules (<30 mm) enter the drum through a feeding mechanism.
2. Heat Exchange: Hot air (temperature ≤750°C) flows through the drum to transfer heat.
Special heat-resistant steel plates are used for high-temperature drying needs.
3. Moisture Reduction: Granules undergo efficient moisture removal through the combined use of lifting plates and hot air streams.
4. Discharge: Post-drying materials exit with consistent moisture levels, meeting industry-specific requirements.
