The production of compound fertilizers involves multiple stages, each requiring specific equipment. The production equipment for different compound fertilizers varies slightly, and the following are the main equipment required for compound fertilizer production:

　　Mixing equipment: used to mix the raw materials evenly, ensuring the uniform fertilizer content of the fertilizer particles as a whole. Common mixing equipment includes horizontal mixers, vertical mixers, double shaft mixers, etc.

　　Crushing equipment: used to crush large raw materials to a particle size suitable for granulation. The crushing equipment mainly includes double roll crushers, vertical crushers, cage crushers, horizontal chain grinders, etc.

　　Granulation equipment: Mix the evenly mixed raw materials into granules through a granulation mechanism. Common granulation equipment includes rotary drum granulators, new toothed granulators, spray granulation dryers, and roller extrusion granulators.

　　Drying equipment: used to dry the moisture in the granulated particles, increase particle strength, and facilitate storage and transportation. Drying equipment mainly includes three drum dryers, spiral drum dryers, electric heating dryers, etc. Meanwhile, drying equipment is usually equipped with dust collectors to collect the dust generated during the drying process.

　　Cooling equipment: The dried fertilizer particles have a high temperature and are prone to clumping, so cooling equipment is needed to cool the particles to a suitable temperature for bagging, storage, and transportation. Common cooling equipment includes cooling machines, and sometimes dust collectors are used for auxiliary cooling.

　　Screening equipment: used to grade the cooled particles, screen out qualified particles, and crush the unqualified particles before re granulation. The screening equipment mainly includes vibrating screening machines, drum screening machines, etc.

　　Coating equipment: Coat qualified particles with coating to increase their brightness and roundness, while also helping to prevent particle clumping. Common encapsulation equipment includes encapsulation machines.

　　Packaging equipment: Quantitatively package the coated particles for easy sales and transportation. The packaging equipment mainly includes automatic quantitative packaging machines.

　　In addition, the compound fertilizer production line also requires the use of belt conveyors, bucket elevators, screw conveyors and other conveyors to transport materials, as well as automatic control systems and detection equipment to ensure the automation level and product quality of the production line.

　　Overall, there are various types of equipment required for the production of compound fertilizers, and the equipment required for production lines of different scales and degrees of automation also varies.
