Introduction of Rotary Drum Cooler
Rotary Drum Cooler is a high-efficiency industrial cooling system designed for the continuous cooling of various materials. As the drum rotates, the material is continuously lifted and tumbled, allowing thorough contact with cooling air for rapid and uniform temperature reduction. It is widely used for fertilizers, minerals, granular materials, biomass, and other products requiring cooling after high-temperature processing. The cooler can be customized according to the material characteristics, processing capacity, and required discharge temperature.
Advantages of Rotary Drum Cooler
01
Fast & Uniform Cooling
Ensures thorough contact between material and cooling air for rapid, uniform cooling.
02
High Processing Capacity
Designed for continuous cooling of large volumes of industrial materials.
03
Customized Design
Engineered to meet specific material, capacity, and discharge temperature requirements
04
High Cooling Efficiency
Optimized lifting flights improve material distribution and air contact.
05
Stable & Reliable Operation
Simple, robust design for continuous operation and easy maintenance.
06
Wide Material Compatibility
Suitable for fertilizers, minerals, granules, biomass, and various hot products.
Working Principle of Rotary Drum Cooler
The Rotary Drum Cooler mainly consists of a feed inlet, support assembly, drum head, rotating drum, lifting flights, and discharge outlet. The specially designed internal lifting flight system is one of the key features of the cooler. It integrates material lifting, flow guidance, and uniform material distribution technologies, ensuring thorough and even contact between the material and cooling air inside the drum for efficient and uniform cooling.
The cooler uses ambient-temperature air as the direct cooling medium, which enters the drum without the need for additional cooling equipment or a separate cooling system. This simplifies the overall process and helps reduce equipment investment. Compared with conventional cooling equipment, the Rotary Drum Cooler can achieve more than 13% higher processing capacity, depending on the material and operating conditions.
