The npk production line for producing npk compound fertilizer includes feeding, mixing, granulating, screening, drying, cooling, packaging and other links. Do you want to know how to make npk compound fertilizer granules?
NPK compound fertilizer granulation equipment is the main equipment for producing NPK granular fertilizer. Such as npk compound fertilizer double roller granulator, npk compound fertilizer disc granulator and npk compound fertilizer drum granulator, etc.NPK fertilizer twin roll extrusion granulator is the most popular granulator among all NPK fertilizer granulator. Why does the public choose a twin-roll extrusion granulator?
The npk compound fertilizer double roller granulator belongs to dry granulation. So you don’t need to use drum dryer and drum cooler to remove moisture from npk fertilizer granules. This will save you production time and the cost of coolers and dryers. Various granule shapes can be selected with the npk fertilizer twin roll extrusion granulator. Such as pillow shape, semicircle shape, rod shape, pill shape, walnut shape, flat shape, square bar shape, etc.
Besides twin roll extrusion granulation, we also have another fertilizer making machine rotary drum granulator to make npk fertilizer granules. Compared with the twin-roll extrusion granulator, there are some different features. Lined with rubber engineering plastics, the raw materials are not easy to stick to the cylinder. Rubber engineering plastics can also play the role of anti-corrosion insulation. This npk fertilizer drum granulator still has the characteristics of large output, low power consumption and low maintenance cost. The particle formation rate of npk fertilizer is as high as 70%, and the amount of returning material is small. And the particle size of the returned material is small, which can be re-granulated. In addition, the drum granulation method is used to make npk fertilizer, no matter the powder fertilizer can be successfully made into granular npk at a temperature lower than or higher than room temperature.
