Is there a more economical NPK fertilizer pellet production machine?

2024/06/19

Summarizing the feedback of our past customers, there are Several kinds of NPK fertilizer granulators that are popular. Pan pelletizer and rotary drum granulation machine. What is the difference between them? The most obvious difference is that they are commonly used on different scales. For example:
For the small scale NPK fertilizer production machine is the disc granulator
If you only plan to start a small scale NPK fertilizer pellets making, we recommend you choose pan pellet machine. A disc granulator can produce 1-6 tons of NPK pellets in an hour. In addition, its granulation rate can reach over 93%. That is, when you use the same amounts of N, P, K to prepare compound fertilizer particles, disc pelletizer can help you granulate more chemical fertilizer powder. There is less material that needs to be returned to re-regulate, so you can finish small scale NPK pelleting effectively.


Drum granulator is suitable for large-scale NPK fertilizer granulation production
There are two reasons. First, it has a larger capacity, which can reach 30 tons/hour. So it can help you complete large-scale NPK granulation faster. On the other hand, the fertilizer machine is designed with rubber lining, Angle iron and cleaning holes. They greatly help to reduce the likelihood of wall sticking. Therefore, the drum granulator can withstand the erosion of a large number of chemical material processing.

There is also the option to purchase our roller NPK fertilizer granulator. If you want to set up a NPK fertilizer production line at a low cost, the roller fertilizer granulator will be your best choice. Because it uses dry granulation, it mainly uses extrusion pressure between two rollers to turn powder NPK into particles, which means that almost no water is involved in the entire NPK fertilizer manufacturing process. So you don't need to spend money on dryers and cooling equipment.

How to further process NPK fertilizer after granulation?
If you want to produce high quality NPK fertilizer pellets, there are also many other fertilizer machines you can use to further process NPK fertilizer after granulation. For example:
Fertilizer granule screener  
When you plan to further improve the quality of your NPK granule fertilizer,the first equipment we recommend you is screener. It can sort the NPK pellets into small fertilizer particles, required size NPK granules and large NPK pellets. Then you can send qualified fertilizer particles to the next step while transport unqualified pellets to re-process. This is greatly beneficial for improving the purity of the final NPK fertilizer pellets you prepare.

NPK fertilizer drying machine
Then, it is also necessary to purchase a drying machine if you granulate NPK with wet pelletizer (pan granulator and rotary drum pelletizer). This equipment can remove excessive water from NPK fertilizer during production.And after drying, the moisture content can be reduced to less than 10%.Therefore, using rotary dryer in NPK wet granulation process can help you make fertilizer which is more convenient for transportation and storage.
NPK fertilizer cooling machine
After NPK fertilizer pellets drying, it is advisable to use a rotary cooling equipment. Why? NPK fertilizer drying mainly makes use of high temperature to dry NPK pellets. This will lead to the discharging temperature of fertilizer reaching 30℃-40℃. So it is not suitable to be packaged directly. At that time, NPK rotary cooler can help you reduce the high temperature to a suitable level quickly.
Automatic packager for NPK fertilizer
Finally, we can provide you with automatic fertilizer packager. It can pack final NPK fertilizer pellets into 10 kg/bag,25 kg/bag, 50 kg/bag, etc. Then you can deliver fertilizer to your correspondent scale customers in an easier way.
