Production process of NPK nitrogen phosphorus potassium compound fertilizer production line

Generally speaking, the NPK nitrogen phosphorus potassium compound fertilizer production line processes nitrogen, phosphorus, and potassium raw materials into nitrogen fertilizer, phosphorus fertilizer, and potassium fertilizer. With years of production and sales experience, Taian Hongxin Environmental Protection Technology can manufacture two complete sets of equipment for nitrogen, phosphorus, and potassium fertilizer production lines. One is the NPK powder fertilizer production line. Its process is relatively simple, requiring batching machines, crushers, mixers, screening machines, and packaging machines. The other is the NPK pellet fertilizer production line, whose key process is granulation. Attention: If you choose wet granulation, such as a rotary drum granulator, your fertilizer production line requires drying and cooling machines.

As is well known, the price of a complete production line must be a key point that all fertilizer manufacturers want to know. It varies depending on the different configurations and models of the devices. The type of fertilizer production is also an important factor. Particle NPK fertilizer equipment is more complex than powder NPK fertilizer. Therefore, the cost is relatively high.

Which machines can be used in the production process of nitrogen, phosphorus, and potassium fertilizers

Taian Hongxin Environmental Protection Technology can provide nitrogen, phosphorus, and potassium production solutions for your fertilizer plant. Generally speaking, there are 5 steps to produce NPK compound fertilizer. The following steps are for reference only in your NPK production process.

NPK material crushing

To avoid some clumping substances in the raw materials, you need to bring them into the crusher. We suggest that you choose a semi wet material crusher. It can crush high moisture materials without dehydration.

Mixed process

Put all the crushed materials into the fertilizer mixer. In the production process of nitrogen, phosphorus, and potassium fertilizers, the uniformity of mixing will directly affect the quality of granulation. If your capacity is large, we recommend using a dual axis horizontal mixer. On the other hand, if your factory is not large enough, you can use a disc mixer with a smaller footprint.

Granulation process

After mixing, the conveyor puts the material into the granulator. This is a critical process, so it is important to pay attention to the differences between various granulators. Two granulation methods are provided, and the double roll extrusion granulator adopts dry granulation. The disc granulator and drum granulator are wet granulators.

Screening process

There are also some impurities or unqualified granular fertilizers. The filtering function aims to select qualified products for the next process. Unqualified products are returned to pre granulation. Two types of screening equipment are used: rotary screening machine and vibrating screening machine.

Packaging process

This is a process for packaging nitrogen, phosphorus, and potassium fertilizers. Prepare single bucket and double bucket automatic packaging scales for your reference.

Overall, the above-mentioned machines have the advantages of advanced technology, reasonable design, and compact structure. In addition, we also provide installation and maintenance methods for nitrogen, phosphorus, and potassium fertilizer production lines. Alternatively, you can customize the machine according to your own situation.
