NPK granulation equipment is specialized equipment for producing high-quality NPK fertilizer granules, and is an indispensable equipment for npk production line. What’s more, NPK granulator plays an irreplaceable role in the process of manufacturing granular NPK fertilizer. Therefore, when you want to build an npk fertilizer production line, you must purchase the most suitable granulator.
1. Double roller extrusion granulator
The double-roll granulator adopts eugenic formula to make NPK fertilizer granules, that is, the finished composite granules are rolled and formed at room temperature at one time. The quality of pellets will meet the requirements of market compound fertilizer technology. When using twin-roll granulator in NPK granulation plant, there are many options for NPK granule shape, including pillow shape, semicircle shape, rod shape, pellet shape, walnut shape and square bar shape. In addition, it can also be equipped with corresponding machines to achieve a certain continuous and mechanized production capacity.
2. Drum granulator
Drum type fertilizer granulator is often used in large npk fertilizer manufacturing process. On the one hand, this machine has a large capacity. 30 tons of high-quality nitrogen, phosphorus and potassium fertilizer granules can be made within one hour of using this machine.
