Product description
Rotary Drum cooler, typically employed in conjunction with dryers. This cooling unit boasts robust cooling capacity, smooth operation, high throughput, and user-friendly handling, making it an essential piece of equipment in organic fertilizer production. It significantly accelerates cooling rates, reduces labour intensity, and enhances output while further lowering the temperature of organic fertilizer and removing surface moisture.
Working Principle
Rotary drum cooler draws in ambient air via its fan connection, where high-temperature particles tumble continuously within the unit. This ensures thorough contact with the cool air, achieving rapid cooling.

Product Advantage
Primarily employed in fertilizer production lines for granule cooling, this unit operates in conjunction with dryers. Its key advantages include:
High cooling efficiency: Rapid temperature reduction achieved through tumbling material within the drum and thorough contact with cold air.
Substantial processing capacity: Suited to large-scale continuous production, meeting high-output requirements of fertilizer production lines.
Stable operation: Featuring a straightforward structure and smooth functioning, it exhibits low failure rates.
Reduced particle moisture: Further removes surface moisture during cooling, enhancing product quality.
Convenient operation and maintenance: High automation levels simplify routine upkeep.
Reduced labour intensity: Enables continuous cooling operations, boosting production efficiency.
