Commonly used compound fertilizer equipment types include three drum dryers, disc granulators, trommels, drum granulators, coolers, disc mixers, etc.
Three-cylinder dryer: a mechanical device that uses heat to reduce the moisture content of materials. It is used to dry objects. The dryer vaporizes and escapes the moisture in the material by heating to obtain solid materials with specified water content. It is mainly used for drying fertilizer with a certain humidity and particle size. Disc granulator: It is used for the production of low and medium content compound fertilizer and the granulation of organic, inorganic compound fertilizer and elemental fertilizer. It is the main equipment for compound fertilizer production.
Drum screening machine: After the material enters the drum device, due to the tilt and rotation of the drum device, the material on the screen surface is turned and rolled, so that the qualified materials are discharged through the screen on the outer circle of the drum, and the unqualified materials are discharged through the end of the drum.
Rotary drum granulator: steam, gas ammonia or phosphoric acid or nitrogen solution, phosphorous ammonia slurry, heavy calcium slurry are added to the machine to complete the chemical reaction and drum granulation process, or supplement The cold granulation process of compound fertilizer with a small amount of water is the main equipment for manufacturing compound fertilizer.
Fertilizer cooler: It is used to cool the fertilizer of a certain temperature and granularity, further remove part of the water and reduce the temperature of the compound fertilizer. It can be used with the dryer to greatly increase the cooling rate.
Pan mixer: Mainly used for mixing raw materials, the materials can be fully mixed, thereby improving the uniformity of mixing and facilitating granulation.
The above are some of the equipment commonly used in NPK fertilizer manufacturing process. The manufacture of compound fertilizer equipment has accelerated the development of modern agriculture, animal husbandry and forestry.
