The fertilizer after dying process need to be cooled to reduce the hot temperature in the production of npk fertilizer and organic fertilizer for imporove production efficiency.

 

   Use drum cooler can greatly improve the cooling rate, reduce labor intensity and improve the quality, further remove moisture, reduce the grain temperature of fertilizer. 

 

   There are Other Supporting process in the npk fertilizer production, hot stove is mainly used for providing the heat source for the drying process, and the cyclone dust collector is used for reducing the dust in the production of fertilizer to protect environment. Belt conveyor is used to transport fertilizer materials in different production process.
