NPK fertilizer is the chemical fertilizer. In NPK fertilizer, the content of nitrogen phosphorus and kalium elements is high. Compared with organic fertilizers, NPK fertilizers are fast-effective. In modern agriculture, NPK fertilizers are absolutely necessary nutrients. Therefore, the future of NPK fertilizer industry is promising. In general, there are two NPK fertilizer processing methods for making NPK fertilizers. The first method is to granulate NPK powdery fertilizer materials into granules. The another method is to blend different ready-made N-fertilizer pellets, P-fertilizer pellets and K-fertilizer pellets. According to these two NPK fertilizer production process, Shunxin experts has designed two types of NPK compound fertilizer production lines: NPK fertilizer granulating lines and NPK fertilizer blending lines.
A NPK fertilizer granulating line consists of crusher machine, fertilizer mixer, granulator, screening machine, fertilizer coating machine and automatic fertilizer packing machine. Compared with NPK fertilizer granulating lines, the NPK fertilizer blending lines are fairly simple. Generally, a NPK fertilizer blending line includes automatic batching machine, BB fertilizer mixer, storage hopper and fertilizer packing machine.
What raw materials you should prepare for NPK fertilizer granules production industry?
We have mentioned that there are two different NPK fertilizer production processes. For NPK fertilizer granulating lines, you need to prepare some chemical powdery materials. For NPK fertilizer blending lines, you must use different NPK fertilizer pellets as the materials. In the following content, Shunxin will introduce the raw materials of the these two different NPK fertilizer production processes respectively.
Raw materials for NPK fertilizer granulating line
The NPK fertilizer is made from powdery chemical materials that contain nitrogen, phosphate and potassium elements. In common, you can use urea, ammonium chloride, calcium nitrate, ammonium sulfate as nitrogen source. What’s more, monoammonium phosphate, diammonium phosphate, calcium magnesium phosphate and triple suprphosphate are often used to provide phosphate elements. In addition, the potassium source for NPK fertilizer include potassium chloride, kainite, potassium sulfate, etc…
Raw materials for NPK fertilizer blending line
The materials for NPK fertilizer blending lines are some different pellet fertilizers. They mainly include monoammonium phosphate pellet(MAP), diammonium phosphate pellet(DAP), potassium sulphate pellet, potassium chloride pellet, urea fertilizer pellet, ammonium chloride pellet, ammonium sulfate pellet, bentonite pellet and so on. The fertilizer formula of NPK fertilizer blending lines is adjustable. Therefore, if you want to invest in NPK fertilizer industry, you can do a research on the soil constituents of your local place.
How to make NPK fertilizer by using fertilizer machines for efficient production?
Honestly speaking, it is up to what kinds of raw materials you are going to use. The NPK fertilizer production technologies of NPK fertilizer granulating line and NPK fertilizer blending line are totally different.
Manufacturing process of NPK fertilizer granulating line
The first step is to crush the materials into fine powder which can be used for granulation process. After this process, if you want to make more nutrient NPK fertilizers, you can use a batching machine to add some microelements into the powder material. Then the batched material should be evenly mixed in a fertilizer mixing machine. Next, it comes the most important part of the whole production line: granulating process.
The quality of powder material and the quality of the fertilizer granulator you use will greatly affect granulation result. So, you should choose high-quality granulator for your fertilizer plant. It is not the final step when you get finished NPK fertilizer pellet. In order to store the fertilizer pellets for long time, the finished pellets will go through drying process, cooling process and coating process. When all these work is done, you can get the completely finished fertilizer pellets. Then you can pack the fertilizer pellets and sell it.
To sum up, the granulating fertilizer production line goes: Crushing→batching→mixing→granulating→screening→drying→cooling→coating→packing. While, if you use the roller type granulation machine for making powdery NPK fertilizer into granules. It is not necessary for you to dry and cool the pelleted fertilizers.
Manufacturing process of NPK fertilizer blending line
Actually, we also call NPK fertilizer blending line as BB fertilizer production line. This is nearly the simplest fertilizer production line. The first step is batching fertilizer pellets with automatic batching machine. In order to get evenly-mixed NPK fertilizer pellets, you need a specialized BB fertilizer mixer. After being mixed, the complex fertilizer pellets will be stored in the storage hopper temporarily. You should place the automatic fertilizer packing machine under the storage hopper. When the fertilizer pellets come out of the storage hopper, they will be packed into bags immediately.
To be short, the blending fertilizer production line goes: Batching→mixing→temporarily storing→packing
