NPK fertilizer production process
In the production of NPK fertilizer, fertilizer plants usually carry out secondary granulation. The application of organic-inorganic compound fertilizer not only controlled the balanced supply of nutrients, but also controlled the stable release of nutrients.
How can it balance fertilization?
It can balance fertilization in the horizontal and vertical directions of nutrients, and improve the utilization rate of nutrients. Granular fertilizer treated by rotary granulator is better than inorganic fertilizer in comprehensive utilization of nutrients.
Rotary drum granulation
In the design of the internal structure of the drum granulator, the function of various internal scrapers is to keep a certain thickness of material on the inner surface of the drum, to make the material layer uniform, and to facilitate the normal rolling and turnover of the material.
Material in the drum
The material in the drum. Steel drums are lined with thermally expandable metal. Rubber baffles and linings, as well as external shock absorbers, are used to prevent accumulation during the drum granulation process. Stable material quantity and uniform liquid phase distribution in rotary drum granulator are the key to produce qualified granules.
