Npk fertilizer production process mainly includes feeder, disc mixer, chain crusher, drum granulator, drum dryer, drum cooler, drum screen machine, finished product warehouse, automatic packaging machine, belt conveyor, dust settling chamber, heat exchanger.

In npk fertilizer production line production of organic fertilizer, the molding particles still have about 30% water, water is too large one is to affect the strength of the particles, in packaging and transportation is easy to crush, on the other hand, water is too large in storage is easy to mold and deteriorate, so in the process to timely organic fertilizer drying treatment, the excess water evaporation, Dryer is an important guarantee of fertilizer quality and storage.

The dryer in the organic fertilizer equipment is specially designed for the production of organic fertilizer. The whole machine is cylindrical, and the special scraping device is used inside to avoid the phenomenon of material sticking on the equipment. It is mainly composed of roller grinding dryer, combustion furnace, feed screw, discharge screw, conveying pipe, dust collector, induced draft fan and control cabinet. It is widely used in organic fertilizer, building materials, metallurgy, mineral processing and other industries. It has advanced production technology and adopts high temperature and rapid drying process, with large heat transfer coefficient, high thermal efficiency and high strength.
