Granular fertilizer is a fertilizer product that has been processed by granulation production process. It has the advantages of uniform particle size, high nutrient content, easy transportation and application, etc. Its production process mainly includes raw material preparation, reasonable proportioning, wet granulation, drying, screening and grading, packaging and storage, etc. The following will combine fertilizer granulation equipment and production line to introduce the production process of granular fertilizer in detail.
In the production process of granular fertilizer, fertilizer granulation equipment is one of the most important process equipment. Common granulation equipment includes disc granulator, drum granulator, double roller granulator, etc.
Disc granulator: The disc granulator uses the rotation and friction of the granulating disc to granulate the raw materials, with a ball formation rate of up to 95%. There are a variety of sizes and models to choose from, suitable for different production requirements.
Rotary Drum granulator: Rotary drum granulator is widely used in chemical, pharmaceutical, food, metallurgy, agriculture and other fields to produce granular products of various powdered or granular raw materials to meet the production needs of different industries.
Double roller granulator:Double roller granulator granulates raw materials through roller pressure, with high efficiency and suitable for small and medium-sized production lines.
Pellet fertilizer production process production line: The production line of granular fertilizer generally includes raw material processing system, mixing system, granulation system, drying system, packaging system, etc.
Raw material batching machine: used for pre-treatment work such as raw material screening and cleaning to ensure the quality of raw materials and batch according to a certain proportion.
Mixer crusher: Mix various raw materials evenly and crush them to the ideal particle fineness to ensure the nutrient balance of granular fertilizer.
Granulator: Through the fertilizer granulation equipment, the mixed raw materials are granulated to form granular fertilizer.
Drying and cooling machine: Dry the granular fertilizer to remove surface moisture and improve the quality of granular fertilizer.
Packaging system: The dried granular fertilizer is packaged, generally including weighing, filling, sealing, stacking and other links.
The production of granular fertilizer can be realized through the continuous operation of the above production processes. The entire production line can be designed and laid out on a large scale according to the different production scales to meet production needs and improve production efficiency.
In general, the production process of granular fertilizer is a complex process that requires strict control of each link to ensure product quality and production efficiency. At the same time, the appropriate selection of fertilizer granulation equipment and production line design can improve production efficiency and product quality, meet market demand, and provide high-quality nutritional support for agricultural production and crop planting.
