The production process of NPK compound fertilizer is an important process of making npk production line. The steps of npk fertilizer manufacturing process are as follows: Crusher, feeder, horizontal mixer, organic fertilizer granulator, dryer, cooler, screening machine, weighing packaging machine . In the last issue, we learned about the crushing process, mixing with a nitrogen, phosphorus and potassium mixer, and making npk compound fertilizer granules. Let us continue to understand the drying, cooling, coating, and packaging of npk compound fertilizer.
NPK fertilizers are dried and cooled. Drying and npk coolers help make the pellets better. If the granules are not dried and cooled after granulation, the temperature and moisture content of the granules will be too high, which is not conducive to storage. Therefore, it is necessary to use a rotary drying and cooling machine. However, if you need a twin-roll extrusion granulator to granulate, you don't need to buy these two machines.
Complete npk compound fertilizer screening and coating. In order to screen out qualified fertilizers or unqualified particles, the rotary screen machine is an essential equipment.
NPK compound fertilizer coating. The pulverized powder or liquid coating process is adopted to effectively prevent the agglomeration of the fertilizer produced by the npk production line. By the way, you can make the fertilizer granules smoother and easier to transport.
NPK fertilizer packaging. This is the last step in the whole process of npk fertilizer production line. It is an automatic packaging scale that is convenient for you to pack fertilizers. Automatic quantitative packaging scale is designed for quantitative packaging. Our designers divide it into double-bucket packing scale and single-bucket packing scale. At the same time, it has the characteristics of scale height, compact structure, high efficiency, novel appearance, convenient installation and maintenance. In addition, the quantitative accuracy of the system is 2‰.
