The High-Efficiency Triple Pass Rotary Dryer (Triple Pass Rotary Dryer) is an energy-efficient drying equipment widely used for drying wet sand, river sand, mineral powder, iron powder, and cement raw materials. It is an optimized design based on the traditional single-cylinder rotary dryer, offering stronger drying capacity and lower energy consumption, making it ideal for drying applications in various industries.
Key Features:
1.Energy-Efficient
The three-cylinder rotary dryer design significantly extends the raw materials’ travel distance inside the dryer, enhancing the heat exchange between the raw material and hot air. Compared with the single-cylinder rotary dryer, the three-pass dryer improves energy efficiency by 50% to 80%.
2.Low Noise and Smooth Operation
Utilizing the friction drive principle, it ensures low noise and smooth operation. For specific applications, a sprocket drive method is also available.
3.Durable Materials
The sand dryer’s drag wheel and roller rings are made of special wear-resistant cast steel to reduce wear and ensure stable operation. The cylinder and internal guide plates are made from 16# manganese steel, offering excellent wear resistance and high strength.
4.Efficient Heat Exchange
The three-pass rotary dryer features multiple guide plates that ensure full contact between the wet sand and hot air, improving drying efficiency. Due to the extended heat exchange time, the outlet temperature of the sand is lower than 80°C, approximately 40°C lower than a single-cylinder dryer.
Why Choose the Triple Pass Rotary Dryer?
●Higher Production Capacity: Compared with traditional single-cylinder dryers, the three-cylinder rotary dryer’s production capacity increases by 50% to 80%.
●Lower Energy Consumption: The evaporation intensity per cubic meter reaches 120-180kg/m³, and coal and natural gas consumption is significantly lower, with energy consumption per ton dropping to just 3-5kg/t.
●Wide Range of Applications: The wet sand dryer is widely used for drying wet sand, mineral powder, iron powder, and other chemical raw materials, especially in cement and foundry industries.
