Introduction of Rotary Drum Cooler
Rotary drum cooler is used to cool fertilizer with certain temperature and particle size in both organic fertilizer and compound fertilizer production. It usually matches with rotary drum dryer to further remove moisture, and lowers the temperature of fertilizer pellets. Our organic fertilizer cooling machine greatly improves cooling speed, and raises product quality. The cooling efficiency of fertilizer pellets cooler will directly influence the appearance and quality of finished products: in compound fertilizer production line, lower efficiency will lead to the caking of compound fertilizer granules. We have improved our cooler design to prevent problems from occurring. Through continuous improvement, Azeus have accumulated rich experience in fertilizer cooler structure, especially the design of shovel plate, which improves cooling rate over 20% than the common cooler and the fertilizer won’t be easy to cake.

Working Principle of Rotary Fertilizer Cooler
Rotary drum cooler belongs to convection cooling equipment. With the rotation of the slightly slanted drum, the fertilizer inside does the same movement. The lifter installed on he inner wall of cylinder continuously lifts the granule materials and then the materials fall by gravity, forming a uniform material stream. Then, it counters with the cool air that is suctioned by induced draft fan and exchange heat, which the temperature of the materials is reduced. The cooled materials flow out from the lower end of rotary drum for further processing by rotary drum screener.
