As the core category of compound fertilizer, the efficient operation of NPK fertilizer production line cannot be separated from the support of advanced equipment. A mature NPK fertilizer production line usually includes the following key equipment, each of which directly affects the quality and production efficiency of fertilizer.
- Batching equipment
Batching is the core link of NPK fertilizer production, and the mixing ratio of nitrogen (N), phosphorus (P), potassium (K) and other elements needs to be accurately controlled. The modern production line adopts an automatic weighing batching machine, which adjusts the amount of raw materials in real time through the PLC control system. The high-precision batching scale can be accurate to the milligram level to ensure the scientificity and stability of the formula.
- Mixing equipment
Mixing equipment is also indispensable, and the mixing uniformity is directly related to the nutrient distribution of fertilizer particles. Powerful Mixers (such as Double Axis Mixers, etc.) can fully and evenly mix the prepared raw materials to avoid uneven nutrient distribution. The unique design of the mixing blades of these mixing equipment can achieve efficient mixing in a short time to ensure that each grain of fertilizer contains balanced nutrients.
- Granulation equipment
Granulation equipment gives NPK fertilizer a suitable shape and also determines the hardness and slow-release performance of fertilizer granules. The Rotary Drum Granulator forms dense granules during rolling through rotational motion and steam conditioning; the Disc Granulator uses centrifugal force to achieve granule classification, and the finished product has a higher roundness. The new equipment can adjust the speed and inclination to meet different formulation requirements, and the production capacity can reach 10-30 tons/hour.
- Drying and cooling equipment
After the fertilizer granules are made, the excess water needs to be removed by drying equipment to achieve the appropriate humidity standard. The Drum Fertilizer Dryer can quickly and effectively dry the fertilizer to prevent the fertilizer from mold and deterioration during storage. The dried granules are then cooled to the appropriate temperature by the Drum Fertilizer Cooler.
- Screening and packing equipment
These equipment ensure the quality of the finished product. The screening equipment screens out qualified particles, removes unqualified parts, and then packs them through automated packing equipment, so that NPK fertilizers can smoothly enter the market and meet agricultural needs. Of course, before packing, coating treatment can also be performed to improve moisture resistance and control nutrient release rate.
From ingredients to packing, every device in the NPK fertilizer production line takes into account efficiency and stability. This not only improves production capacity and quality, but also reduces operation and maintenance costs.
