The compound fertilizer production line is a series of equipment combinations used to process various fertilizer raw materials into compound fertilizers. Its process flow encompasses multiple stages, including raw material batching, mixing, granulation, drying, and cooling. Below is a detailed introduction:

main equipment

Automatic batching system: Composed of a feeding system, weighing device, storage bin, and conveyor belt, it enables precise material batching.

Belt conveyor: Used for transporting raw materials and finished products, featuring functions such as movement and elevation, and can be flexibly arranged according to on-site conditions.

Mixers: There are disc mixers, double-shaft humidification mixers, etc., which can thoroughly stir and mix the raw materials.

Granulator: such as drum granulator, disc granulator, etc., is the key equipment for converting raw materials into pellets.

Drying Machine: Commonly used rotary drum dryers can be employed for granular material drying.

Cooler: Typically employs a rotary cooler to reduce particle temperature and prevent caking.

Sieve machine: such as the drum sieve, used for particle classification and screening.

Coating machine: Rotary coating machine, capable of performing coating treatment on granules.

Packaging Scale: Includes automatic quantitative packaging scales, conveyors, and sealing machines, enabling the quantitative packaging of finished products.
