NPK fertilizer production line factory direct sales
As we all know,the plants needs so many more nutrients than nitrogen,phosphorus and potassium(also called NPK). While the current soil can't supply adequate nutrients because of the soil erosion,pollution and other problems.Now more and more farmers expect to plant comprehensive NPK fertilizer for larger yield of their plants,which has promoted more factory to produce NPK fertilizer with good quality.Our company can provide various systems and equipments to convert raw feedstock to marketable and valuable fertilizer.
What's the raw materials can be used to produce NPK fertilizer
1.As the source of nitrogen,urea,ammonium hydrogen carbonate,ammonium chloride,ammonium sulfate,ammonium nitrate and other materials which are rich in nitrogen are the best choice
2.As the source of phosphorus,superphosphate,triple superphosphate,mono-ammonium phosphate,diammonium phoaphate are the best choice.
3. Potassium sulfate,potassium chloride can be selected as the ideal source of potassium.
4. Some fertilizer maybe require micro nitrient ,various options such as Bo,Zn,Mn can be done,it all depends on the soil testing and fertilizer fomular.
Production process of NPK fertilizer
1.Batching :All kinds of raw materials will be fed into the electronic belt scale by which will measure the weight and ratio of each raw material exactly .It is controlled by automatic computer.
2.Granulation:the raw materials will be fed into the granulator to make into fresh granules.
3.Drying:After granulation, though granules has been formed, but right now its moisture is too high, so they will be conveyed to the rotary dryer for drying.
4.Cooling:The temperature of the granules coming out of the dryer is quite high, then the granules will be send to the rotary cooler for cooling to further increase the granules strength and reduce the moisture.
5.Sieving:After cooling, the granules will be pass the sieve to separate coarse granules and fine powder, final product will be achieved. The big granules and the fine powder will go through the grinder and recycle to the granulator, which will make them participate in the granulation process again .
6. Coating :The granules after sieving will be sent into coating machine to spray a film on the granules surface ,which can protect the granules with the air .
7.Packing :After coating ,the granules will be delivered to automatic packing machine and then storage in bulk.
Remark: This granulation process can be used for producing various kinds of fertilizer, includes NPK fertilizer, organic fertilizer, humic acid fertilizer and controlled release fertilizer etc, it can be used for hundreds of formulas of fertilizer .This production line is a multi-function production line.
Traits of NPK compound fertilizer making equipments
