Generally speaking, NPK fertilizer production line is to process the three materials of N, P, K to produce the nitrogen fertilizer, the phosphorus fertilizer and the potash fertilizer. To choose reasonable equipment can help you enhance the production efficiency. With many years producing and selling experience of, Yuheng can manufacture two complete equipment for npk fertilizer manufacturing line. One is NPK fertilizer granule blending production line. Its process is relatively simple, which need the batching machine, mixing machine and packing machine. The another is the NPK pellet fertilizer production line, whose key procedure is granulating. Notice: if you choose the wet type granulation like rotary drum granulator, there needs the drying and cooling machines in your fertilizer production line.
NPK fertilizer granule blending production line
Batching process: At the beginning, you should put all the straight fertilizer into the dynamic automatic batching machine on the basis of the proportion. After finishing the batching, the raw materials will be transport to the next process by the belt in the batching machine.
BB fertilizer mixing process: With the movement of conveying belt, the batched single manure is sent to a BB fertilizer mixer. Here, fertilizer mixer will fast mix all straight fertilizer until materials get into a state of even. Then conveyor will deliver the mixed bulk-blending fertilizer into next procedure.
Packing process: In the process. if the capacity is large, the mixed fertilizer will be first transported into a storage hopper and then flow into the automatic packing scale. You can set the weight you want like 20kg, 25kg, 30kg and so on.
NPK pellet fertilizer production line
Materials proportion：The Raw materials such as urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate (monoammonium phosphate, diammonium phosphate, heavy calcium, calcium), potassium chloride (potassium sulfate) are proportioned by certain ratio (according to market requirement and local soil testing results).
Materials mixing：Mix the proportioned materials evenly and improve fertilizer efficiency.
Materials granulation： Feed the stirred materials into the granulation machine. ( Rotary drum granulator and extrusion granulator are both available).
Granules drying： Feed the granulated materials into drying machine and dry the water of the granules. Thus enhance the granule strength and make it easy to store.
Granules cooling：The dried fertilizer granules has excessive temperature and are easy to caking. Then the granules need to go through the process of cooling for convenient storage and transportation.
Granules classification.：The cooled granules need to be classified. The unqualified granules must go through granulating again. Then screen out the qualified products.
Finished products coating： The qualified products need to coated, so as to improve the brightness and roundness of the granules.
Finished products packaging：Pack the coated granules and store the finished products in ventilated places.
