As the continuous development of society and the continuous improvement of science and technology, China's economic level has been greatly improved, and people's living standards have also improved a lot. Various factors provide great convenience for the development of agriculture.

Rotary drum granulator belongs to one of the key fertilizer granulating equipment for making compound fertilizer granules which is applied to both cold and heat granulation with high,medium and large scale production.This compound fertilizer granulator can make both low and high concentrations of compound fertilizer granules.The finish inside of the rotary drum granulator is made by a special polyethylene resistant rubber sheet.The rotary granulator has advantages of high rate compound fertilizer granulation rate, good appearance, corrosion resistance, low energy consumption, easy operation and maintenance, except this kind of drum granulator, our mutifunctional double roller granulator can also make compound fertilizer.The high efficiency fertilizer granulation machine is considered as the most important equipment in large scale compound fertilizer production. By adding a certain number of steams and vapors, raw materials in the rotary drum granulator will become uniformly humid during the granulation process. Then a series of chemical reactions will occur. In this rotary granulator machine, the fertilizer particles squeeze each other and roll into fertilizer particles. The uniformly formed fertilizer particles can be 3-8mm. With the continuous adding of raw materials and rotating of the drum, a large scale production as well as the working efficiency will be insured.

 

In organic fertilizer production line, we can mix raw materials with fertilizer mixer machine and then we can use the rotary drum granulator machine which it is also to be equipped in npk fertilizer production line to finish the production process of the npk fertilizer granulator.
