Spray granulation production line

Spray granulation production line Introduction

Spray granulation is the process of spraying water (a general term for vaporized liquids) from a slurry (mixture, solution, and solute) into a device, using heating and compression methods to vaporize and separate the water in the slurry, and then form granular solid that does not vaporize (under certain conditions). Specifically for the production of compound fertilizers, the spray granulation process usually involves spraying molten urea or other nitrogen-containing substances into the compound fertilizer granulation device, mixing them with other raw materials such as phosphorus fertilizer, potassium fertilizer, etc., and forming granular fertilizers through the rotation and extrusion of the granulator.

Main Technical Parameters

We have multiple production cases of compound fertilizer spraying and granulation, with mature technology, and can customize a compound fertilizer spraying and granulation production line with an annual output of 10000 to 500000 tons for you.
main features
Uniform nutrient distribution: During the spraying and granulation process, various raw materials are thoroughly mixed to make the nutrient distribution in the compound fertilizer more uniform, which helps crops better absorb and utilize nutrients.
Smooth and round particles: Due to the combination of spraying and granulation, the surface of compound fertilizer particles is smoother and the shape is more regular, which is conducive to improving the appearance quality and market competitiveness of fertilizers.
Low production cost: Compared to traditional compound fertilizer production processes, the spray granulation process reduces some production steps and lowers production costs.
Environmental protection and energy conservation: This process generates less pollutants such as exhaust gas and wastewater during the production process, which meets the national requirements for environmental protection and sustainable development.
