Ordinary superphosphate (SSP) is a water-soluble and quick acting phosphate fertilizer with an effective phosphorus content of over 16%. This product can be used as a base fertilizer, topdressing fertilizer, seed fertilizer, and raw material for producing compound fertilizers; Widely applicable to various grain and economic crops such as rice, wheat, corn, sorghum, cotton, fruits, vegetables, etc; Widely applicable to various soil types such as red soil, yellow soil, brown soil, yellow tide soil, black soil, brown soil, purple soil, and white mud soil.
The SSP fertilizer production line is an important technology in modern agricultural production, and its process includes steps such as raw material preparation, mixing and stirring, and material granulation. The equipment required for this production line includes raw material storage yards, crushers, mixers, etc. Its advantages lie in efficient and stable production capacity, energy conservation and environmental protection, and strong product adaptability.
Raw material preparation:
Select urea, ammonium nitrate, ammonium chloride, etc. as nitrogen sources; Ammonium sulfate and ammonium phosphate as phosphorus sources; Potassium chloride or potassium sulfate are used as potassium sources.
Accurately mix ingredients based on soil testing results and market demand.
Mixing and stirring:
Mix the prepared raw materials evenly to improve the overall uniform fertilizer efficiency of the fertilizer particles, usually using a horizontal mixer or a disc mixer for mixing and stirring.
Material granulation:
Send the mixed and evenly mixed raw materials into the granulator through a conveyor for granulation. The available types of granulators include drum granulators, roller extrusion granulators, or disc granulators.
Particle drying and cooling:
After granulation, the particles need to be dried to meet the moisture requirements of national standards, and operated using a rotary drum dryer. Subsequently, cooling is carried out to reduce the particle temperature and facilitate subsequent processing.
Particle grading and encapsulation:
Grading the cooled particles, re crushing and granulating the unqualified particles, and coating the qualified products to increase particle brightness and roundness, thereby enhancing market competitiveness.
Final packaging:
The finished particles that have been coated with film are sent to the silo for temporary storage by a conveyor, and finally quantitatively packaged and sealed using automated packaging equipment for storage or sales.
Equipment required for SSP fertilizer production line:
Raw material storage yard:
Used to store raw materials for organic fertilizer production, to prevent moisture or excessive exposure to sunlight.
grinder:
Used to crush large raw materials into fine particles for subsequent processing. According to different raw materials, different types of crushers can be selected, such as hammer crushers or drum crushers.
blender:
Double shaft or vertical mixers are common choices for thoroughly mixing crushed raw materials with microbial agents or other additives.
Fermentation tank:
One of the core equipment, used to ferment the mixed raw materials under specific conditions and convert them into organic fertilizers. Different scales of production will choose fermentation tanks of different specifications.
Granulator:
Make the fermented organic fertilizer into granules for packaging and transportation. According to product characteristics and user needs, disc granulators or extrusion granulators can be selected.
dryer:
Used to remove excess moisture from fertilizer after granulation, improving product quality and stability. You can choose between natural air drying or mechanical drying.
packer:
Used for packaging dried organic fertilizers, selecting suitable packaging methods and equipment according to market demand.
Control system:
This includes sensors, instruments, and control software to achieve automated control and data-driven management of the production process, improving production efficiency and product quality.
Efficient and stable production capacity:
The design of the production line is scientific and reasonable, ensuring the continuous and stable production process and improving production efficiency.
Energy conservation and environmental protection:
Adopting advanced technology and equipment, reducing energy consumption and waste emissions, and achieving clean production.
Strong product adaptability:
Production strategies can be adjusted according to different market demands and raw material conditions to flexibly produce various types of compound fertilizers, including organic fertilizers, inorganic fertilizers, biological fertilizers, etc.
