In general, the dry granulation is usually adopts in small scale NPK fertilizer plant, because it need a simple granulator to process its low capacity. Besides the low capacity, the dry granulation do not need dryer and cooler. Instead, commercial nitrogen fertilizer production adopts the wet granulation.

The dry granulation has a larger capacity and a complete process. If you want to set up a nitrogen fertilizer factory with small capacity and capital, you can choose the dry granulation method. For those who are planing to build a commercial nitrogen fertilizer plant, wet granulator is a great choice.

If you are interested in dry granulation and want to produce nitrogen fertilizer, the double roller granulator is the best suitable machine. The whole production line consists of the double roller granulator and other auxiliary equipment. If you want expand your production, you only need buy one extra granulator in your line.

Our double roller is an equipment for compound fertilizer production. It can consume low energy to produce high quality nitrogen fertilizer pellets. For the granule diameter, you can choose 3-10mm. We offer 1t, 1.5t and 2t capacity roller press granulator.

Due to the dry granulation, the whole process of double roller granulator has less production steps. Such as it not need drying and cooling process. That’s to say, it can help you save the cost of dryer and cooler. In addition, the double roller granulator has lower price than other wet granulators

Is only the nitrogen fertilizer can use the double roller granulator? In fact, like zinc sulfate, potassium sulphate(SOP), potassium chloride, ammonia chloride, ammonia sulfate, magnesium sulfate, and sodium chloride,etc are suitable for making compound fertilizer using the double roller granulator.

The above is a brief machine of the outlay of the nitrogen fertilizer dry granulation line. As an NPK and organic machinery manufacturer, we provide various types and models of NPK or organic fertilizer machines, such as smart blender machine, fertilizer crusher, and various granular fertilizer machine.

When you put you nitrogen powder into our disc granulator, on the top of the pan, there will be a water sprayer to wet your nitrogen powder. Then through the pan rotates, the wet nitrogen powder will be rolled into small particles. More important, due to the binding effect of water, these particles are not easy to break down. The whole granulation process is in open air, you can see the process. When there is some problems, you can adjust the angle device instantly. For instance, when your nitrogen powder is too dry to granulate, you can add more water through the water sprayer.

What do you need to build a commercial nitrogen fertilizer plant? A large output granulator is important. Our rotary drum granulator is your top choice, because its max capacity can reach 30t/h. how does our drum granulator realize the mass production? First, the working principle adopts wet granulation. The nitrogen powder forms granules in the one-time forming spiral barrel. The drum is able to make nitrogen fertilizer powder into small balls by centrifugal force after a series of chemical reactions takes place.
