There are two types of NPK fertilizer in forms. One is granular NPK, and the other is powder forms. Actually, NPK fertilizer manufacturers sell moreNPK granular fertilizer in the fertilizer market. But why? Let's compare these two types of NPK compound fertilizer.
Powder NPK Fertilizer Production Line
When fertilizer manufacturers produce powder NPK fertilizer, they will use a fertilizer crushing machine to crush two or three kinds of straight fertilizers.After crushing, they use the fertilizer screener to screen out the bulk fertilizer. Then the qualified powder fertilizer will be metered by precise batching machine according to the scientific calculated compound fertilizer formula. Next, fertilizer producer put these powder fertilizers into mixing machine in order to mix them evenly. At the end, uniform fertilizer can be sold out of the factory after packaging. Granular NPK Fertilizer Production Line
Granular fertilizer is a secondary processing on the basis of powder fertilizer production process. By using granulators, you can produce different shapes of granular fertilizer to meet the needs of the fertilizer market. After granulation, in order to meet the sales standards, you should use fertilizer dryer to remove extra After drying,there will be the fertilizer caking because of high temperature.Therefore, you need to apply the fertilizer cooler to reduce the temperature. To be clear, if you apply dry granulation, you do not need to drying and cooling these two processes. Next, to improve the nutrient utilization rate of fertilizer, makers will use compound fertilizer coating machine to coat the granular fertilizer. Finally, they pack the coated fertilizers and sell them out of the factory.

Cost Of Producing Powder Npk Fertilizer：Through the above production process of powder NPK compound fertilizer, it is obvious that the production process of powder NPK fertilizer is simple. You just need a few the fertilizer production mechanical equipment in powder NPK fertilizer production line.All in all, the cost of producing powdered NPK is low.
Cost Of Producing Granular Npk Fertilizer：NPK granular fertilizer production process includes granulation, drying, cooling and so on, so the composition of NPK production line is more complicated. Hence you need a variety of fertilizer production equipment to assemble theNPK Granular Fertilizer Production Line . The cost you need to invest will also be high.
After comparing the above three aspects, both types ofNPK fertilizers have their own advantages and disadvantages. But NPKgranular fertilizer can bring more benefits to fertilizer manufacturers. So, we more recommend you to produce granule NPK compound fertilizer.
