NPK Granulation Tech

Granulation technology of NPK fertilizer production line with rotary drum granulator

Rotary drum granulator is the main granulating equipment of NPK fertilizer production line. It uses powder composition and agglomeration granulation method to make NPK compound fertilizer molding. The drum granulator developed by our factory adopts a new generation granulation technology, which improves the formation rate of compound fertilizer granules and the qualified rate of primary granulation.

Rotary drum granulator

The rotary drum granulator can make NPK compound fertilizer into granules, which is easy to store and release, thus greatly prolonging the fertilizer utilization rate of organic fertilizer. The drum granulator is suitable for cold and hot granulation. It uses aggregate wet granulation, and adds a certain amount of water or steam to the cylinder, so that the extrusion force between the material particles can be condensed into a ball.

Granulation technology of NPK fertilizer production line

In order to improve the granulation performance of rotary drum granulator, we improved the drying process of NPK fertilizer production line after granulation. It can shorten the drying time of fertilizer production, minimize the damage of compound fertilizer particles in the drying process, and increase the numNPK Granulation Tech

For NPK fertilizer granulation, the quality of granulation particle size depends on the proportion and feedback granularity to a certain extent. Compound granulation usually needs batch quality, and the quality of returned materials is the key to control the production of rotary drum granulator. On the basis of ensuring nutrients, the quality of returned materials mainly depends on the size and distribution of returned materials. In order to ensure the quality of returned materials, we set up chain crusher in NPK fertilizer production line.

The chain crusher will re crush the unqualified returned materials, and the crushed powder can meet the granulation requirements of the rotary drum granulator.
