Efficient and stable NPK fertilizer production line has become the key for enterprises to seize the market. As a Chinese foreign trade enterprise deeply engaged in the field of fertilizer equipment, our 3-5t/h NPK fertilizer production line provides an ideal solution for global fertilizer manufacturers with advanced technology and excellent performance. ​
Precise proportioning, casting the foundation of quality. The production line is equipped with a high-precision weighing and batching system, using dynamic metering technology and PLC intelligent control, and strictly controlling the proportion error of nitrogen, phosphorus, potassium and other macro-element raw materials and trace element additives within ±0.3%. According to different soil conditions and crop requirements, the formula can be flexibly adjusted. Whether it is a special fertilizer for field crops or a formula fertilizer for fruit and vegetable economic crops, it can be accurately produced with one button to ensure balanced fertilizer nutrients and meet the diversified needs of the market. ​

Efficient and stable, improve production efficiency. From raw material crushing, screening, mixing to granulation, drying, cooling, and packaging, the whole process equipment is closely coordinated. The double-axis gravity-free mixer can achieve full and uniform mixing of materials within 3 minutes, with a mixing uniformity of ≥99.5%; the core granulation process adopts roller extrusion or disc granulation technology, which can stably produce 3-5 tons of high-quality fertilizers with full particles and strength of 8-10N/particle per hour, which is 60% more efficient than traditional production lines and effectively reduces unit production costs. ​
Intelligent environmental protection, practice green production. The production line is equipped with an automated control system, which can realize parameter setting, operation monitoring and fault warning through the touch screen, and also supports remote debugging, which is convenient and efficient to operate. The fully enclosed negative pressure dust removal system and the deodorization device work together to control dust emissions below 8mg/m³, which meets international environmental protection standards; the waste heat recovery technology in the granulation and drying process enables the recycling of heat energy, reduces energy consumption by 35%, and has significant green energy-saving advantages. ​
Real cases witness strength. After a Brazilian fertilizer company introduced a 3-5t/h NPK fertilizer production line, the product qualification rate increased from 82% to 97%, and the annual production capacity increased by 12,000 tons. With stable product quality, it successfully opened up the Middle East market; after the agricultural cooperative in South Africa used the production line, the production cost was reduced by 28%, and the fertilizer produced was in short supply locally, which led to an increase in production and income for surrounding farmers. ​
We provide one-stop services from site planning, equipment installation to operation training and after-sales maintenance, and support multi-language operation interface customization.
