In order to make fertilizer NPK 17:17:17, many fertilizer manufacturers will choose make it with the fertilizer production line. Through the fertilizer making plant, you can monitor the production status in real time during the production process and make continuous adjustments. The result can produce high quality 17:17:17 NPK fertilizer.

Method for Making 17:17:17 NPK Fertilizer

What is the manufacturing process options for 17:17:17 NPK fertilizer? Here is a method for you to choose–17:17:17 NPK fertilizer granulating production line. Then our professional engineer will introduce it for details.

High Precision Batching System for 17:17:17 NPK

How to make the proportion of N,P,K for your formula——17:17:17? Our high precision batching system can help you feed these materials through electronic belt scale. And this system also configure the electric control box, which can ensure that the ratio error does not exceed 1%.

Crushing the 17:17:17 NPK Raw Material

17:17:17 NPK fertilizer contains 17% nitrogen (min total nitrogen), 17% phosphorus, and 17% potassium. You need to uniform these raw materials’ size below 3mm in your production line. This can be convenient for you to make fertilizer. So you need to crush them to get a better state for further make fertilizer. Here are two crushers you can choose according to you need–cage crusher and chain grinder.

Mix the Powdery Material for 17:17:17 NPK

After crushing the raw material, you can add some ammonia. It can promote granulation and improve product quality by increasing the CHR(critical relative humidity) and decreasing the acidity. This effect can be achieved by fully mixing ammonia and 17:17:17 NPK materials.

17:17:17 NPK Granular Fertilizer Production

Granulation process plays an important role in your 17:17:17 NPK fertilizer making plant. According to the dryness and wetness of your 17:17:17 NPK material, you can choose two granulation methods – dry granulation or wet granulation. In general, if your material is dry, you can use a double-roll granulator to granulate it. But if your materials’ moisture is 45%-50%, you can choose a drum granulator.

Dry and Cool the 17:17:17 NPK Granular Fertilizer

If you use double roller granulation machine, you do not need to dry and cool. But for the rotary drum granulator, you’d better use dryer and cooler to decrease the excessive moisture from the 17:17:17 NPK fertilizer. The capacity of the dryer is 1-18 tons, and you can choose different types of equipment according to your output. During the operation of the dryer, a large amount of exhaust gas will be generated. So you can install a dust collector, which can effectively guarantee the production environment.

Polishing the 17:17:17 NPK Fertilizer with the Perfect Shape

After drying and cooling, the 17:17:17 NPK pellets are deformed to some extent. In order to make the particle shape more beautiful, a rounding machine is essential. Because the high-speed rotation of the two discs shape the pellets. If you still need color, you can add colorant during the rounding process.

Package Equipment to 17:17:17 NPK Fertilizer

In order to facilitate the transportation and sale of your finished 17:17:17 NPK fertilizer, packaging is necessary. So our automatic packaging machine can help you complete the packaging more conveniently. And the single-bucket and double-bucket packaging machines with a capacity of 20-50kg are available for you to choose.
