What Other Machines Do You Need After Granulation For Setting Up The Urea Based Compound Fertilizer Production Line?
To get the quality urea based compound fertilizer, you should still process the granulated fertilizer. There are still four processes you should know after granulation. You also need to deploy the machines for drying, coating, screening and packing. The detail descriptions are as follows.
After the granulating process, you will get the urea based compound fertilizer granules with the temperature of 60 ℃ and the moisture of 2.5%. In order to improve the strength of the fertilizer granules, you need to use the rotary drying machine to reduce the extra moisture.
Because the nitrogen element of compound fertilizer will start to hydrolyze at 60 degrees, and too high temperature will accelerate the formation of biuret which is harmful for the crops. The above two problems will lead to the destruction of nutrients in compound fertilizers. Therefore, you should control the drying temperature at the range of 60℃-70℃.
Because raw materials such as urea will undergo a hydrolysis reaction under conditions that contain a certain amount of moisture. And this reaction still occurs during storage. Such a reaction can cause the product to agglomerate. In order to avoid this situation, you need to reduce the moisture of the urea based compound fertilizer pellets to less than 2%.
As mentioned above, you also need to buy other four machines to set up the urea based compound fertilizer production line. When purchasing these machines, you can contact with us. We will give you some reasonable suggestions about the machine’s selection.
