What is a Rotary Dryer?
A rotary dryer is an industrial drying machine that reduces moisture content in bulk materials through a combination of heat, rotation, and gravity. The equipment consists of a large rotating cylindrical drum mounted at a slight angle, allowing material to move through the system while being exposed to hot air or gases.
How Does a Rotary Dryer Work?
- Material Feeding: Wet material enters the dryer through the feed hopper
- Rotation & Lifting: Internal flights lift and cascade material through hot gas stream
- Heat Transfer: Direct or indirect heat removes moisture content
- Material Discharge: Dried product exits through the discharge end
- Dust Collection: Exhaust gases pass through dust collection systems
Types of Rotary Dryers We Manufacture
1. Direct Rotary Dryers (Co-current & Counter-current)
Direct dryers bring materials into direct contact with hot gases for efficient moisture removal. Ideal for materials that can withstand high temperatures.
Applications:
- Sand drying
- Mineral processing
- Chemical powders
- Agricultural products
2. Indirect Rotary Dryers
Indirect dryers heat the drum externally, preventing contact between materials and combustion gases. Perfect for heat-sensitive or contamination-prone products.
Applications:
- Pharmaceutical ingredients
- Food products
- Fine chemicals
- Specialty materials
3. Triple Pass Rotary Dryers
Three concentric cylinders rotate together, maximizing heat transfer efficiency and reducing footprint requirements.
Advantages:
- Higher thermal efficiency
- Compact design
- Consistent output quality
- Lower energy consumption
