Rotary Drum Dryer
Triple-Pass Drying Efficiency: Materials pass through three concentric cylinders, extending drying time and improving overall drying performance.
Excellent Thermal Insulation: The nested drum design minimizes heat loss and enhances energy efficiency through optimized heat exchange.
Compact Structure: Occupies only half the space of a traditional single-drum dryer with equivalent capacity, reducing land and infrastructure costs.
Reliable and Easy to Automate: Stable operation with fewer manual interventions, ideal for automated production lines.
Low Energy Consumption: Efficient internal heat distribution reduces fuel usage, lowering operating costs.
Product Introduction
The new three-pass rotary drum dryer adopts advanced technology and features three concentric cylinders of different diameters nested together. Materials are distributed across these three drum layers, where they receive heat at varying temperatures. The unique heat transfer method within each drum enhances thermal insulation and significantly reduces heat loss. This efficient, integrated design offers a compact structure and occupies only half the floor space of a single-drum dryer with the same output. It is reliable in operation, energy-efficient, highly thermally efficient, ensures excellent drying results, and is easy to automate with minimal staffing requirements.
Dryer Components
The dryer system is composed of the following equipment:
Hot air furnace
Belt conveyor (self-supplied)
Rotary airlock inlet/outlet valves
Main drying drum
Fan
Cyclone separator
Electrical control cabinet
Performance Advantages
High Drying Efficiency: The three-layer structure allows material to travel through three passes, extending retention time and enhancing drying performance.
Reduced Energy Consumption: The special internal design allows for more efficient heat exchange, lowering energy usage.
Space-Saving Design: The compact layout of the entire production line reduces the required floor area, saving land costs.
