What is key equipment in the NPK fertilizer production line? -Different granulators for NPK fertilizer plants.
In fact, the key machine is the fertilizer granulator in the NPK fertilizer manufacturing process. Even in the NPK fertilizer mixing production line, we have to use single element fertilizer particles. However, the cost of single fertilizer pellets will be higher than that of powdery fertilizer. Therefore, buying a fertilizer granulator will be the right choice, because it will save you more operating costs in a long time. But how to choose a granulator suitable for your fertilizer plant?
Dry and wet granulator for NPK fertilizer production.
In the NPK fertilizer manufacturing process, if you want to use a dry granulation machine, you need to control the moisture of your raw materials about 10%. And an obvious advantage of using a dry granulator is that you do not need to buy a dryer and cooler. Here, we recommend you use double roller granulator. And it is a multifunctional granulator for various fertilizer making with different shapes.
However, for some NPK fertilizer manufacturers, they want to purchase a wet type granulator. Because using wet granulator will not produce dust. In addition, the wet type granulation machine price is lower than double roller granulator. And, in SX machinery, you can choose right one between pan granulator and rotary drum granulator.
