NPK fertilizer production line
Npk production line overview:
NPK production line is a production equipment specially designed for the production of NPK compound fertilizer.NPK compound fertilizer is a kind of fertilizer containing various nutrients such as nitrogen (N), phosphorus (P) and potassium (K) at the same time, which is usually used to provide comprehensive nutritional needs of crops.
NPK fertilizer production line raw materials:
1, nitrogen source (N):
Urea, ammonium salt, ammonium nitrate and so on.
2, phosphorus source (P):
Phosphoric acid, diammonium phosphate, phosphate powder, etc.
3、Potassium source (K):
Potassium chloride, potassium sulfate, sodium chloride, etc.
Trace elements and additives.
- Mixing stage:
Mixing of raw materials: Nitrogen (N), phosphorus (P), potassium (K) and other raw materials will be mixed according to a specific formula using dosing machinery (dynamic dosing scale, static dosing scale). The mixing ratio of raw materials will be adjusted according to the NPK content of the target fertilizer and crop demand.
- Grinding stage:
Grinding: Mixed raw materials through the grinding equipment (vertical mill, hammer mill) into powder for subsequent granulation.
- wet granulation stage (drum granulator, disk granulator):
Wet granulator: the crushed raw materials through the drum granulator, add the appropriate amount of water, the use of high-speed rotation of the drum to make the raw material to form particles.
- Drying and cooling stage:
Rotary drying: the wet granulation of the particles through the drum dryer for drying, reduce the moisture content of the particles, and then through the cooling machine to reduce the temperature, so that it is suitable for storage and packaging.
- Sieving stage:
Sieving: The dried granules are sieved through vibrating sieving machine to ensure uniformity and conformity to specifications.
- Dry granulation stage (Roller granulator):
Roller pelletizer: Feed the pellets into the roller pelletizer to form denser pellets through the squeezing pressure of the rollers and the rotary movement of the squeezing wheel.
- Dry pelletizing post-treatment stage:
Rounding: Roller pelletizing products are mostly flat, if you need more rounded particles finished product, you can add rounding machine for fertilizer particles rounding.
Sieving: Use vibrating sieving machine to sieve the granules after dry granulation to ensure the uniformity of the granules and meet the specifications.
- Micronutrient addition and packaging stage:
Addition of trace elements: At the final stage of granulation, trace elements can be added to improve the comprehensive nutritional value of the fertilizer.
Packing: The finished granules will be packed, either in bulk or in bags for easy transportation and use.
- Control system:
Automatic control: The whole production line is usually equipped with an automatic control system that monitors and adjusts the operation of each stage to ensure the stability of the production process and product quality.
This process combines wet and dry granulation technology, which is more flexible to adapt to different raw materials and production requirements, and at the same time ensures that the output of NPK compound fertilizer particles with balanced nutrients, stable quality, and at the same time, has the appropriate physical characteristics.
Equipment additions and improvements:
NPK production line advantages:
1、Precise proportioning:
NPK production line can achieve accurate nutrient proportioning through advanced automated control system to ensure that each batch of compound fertilizer meets the specific formulation requirements. This helps to provide high quality and consistent products.
2.Improve production efficiency:
The production line with PLC centralized control system can significantly improve production efficiency, reduce manual operation and lower production costs. At the same time, the highly integrated production process can realize the continuous production from raw material preparation to the final product, which further improves the overall efficiency.
3, flexible to adapt to market demand:
NPK production line has a certain degree of flexibility to adapt to the needs of different markets and customers. By adjusting the formula and production parameters, the production line can produce compound fertilizers suitable for different crops, different growth stages and different soil types.
4、Improve product quality:
Precise nutrient distribution ratio, consistent particle size and shape, and adequate mixing homogeneity all help to improve the product quality of NPK compound fertilizer and meet the requirements of agricultural production for efficient fertilizers.
Overall, the NPK production line provides an efficient, flexible, environmentally friendly and high-quality npk fertilizer production solution by integrating advanced technology and automation systems. Henan Lane Heavy Industry Science & Technology Co., Ltd, as an original manufacturer of fertilizer equipment with three decades of experience, is able to provide customers with comprehensive solutions to meet their production needs and realize the “low investment, high return” fertilizer manufacturing industry.
