The fertilizer granule coating machine is one of the indispensable and important equipment in modern fertilizer production. It is widely used in the production and processing of compound fertilizer, organic fertilizer, and other granular fertilizers. With the continuous improvement of agricultural requirements for fertilizer quality, coating technology has become an important means to improve fertilizer utilization, extend fertilizer effectiveness, and reduce nutrient loss. In this article, we will introduce in detail the functional characteristics, working principle, and important role of the fertilizer granule coating machine in the fertilizer industry.
Function of Fertilizer Granule Coating Machine
The Fertilizer Granule Coating Machine is a device specially used for coating the surface of granular fertilizer. By adding a protective film to the fertilizer granules, the following functions can be achieved:
- Extend the fertilizer's effect time
The coating technology controls the release rate of fertilizer nutrients to avoid waste caused by too fast release of nutrients, thereby extending the effective time of fertilizer.
- Improve fertilizer utilization rate
Coating can reduce the volatilization and loss of fertilizer, increase the proportion of fertilizer absorbed by crops, and improve the fertilizer use effect of a unit of fertilizer.
- Reduce environmental pollution
Traditional fertilizers are prone to nutrient loss in the soil and even pollute water sources. Coating technology significantly reduces the adverse effects of fertilizers on the environment.
- Improve fertilizer fluidity
The surface of the coated fertilizer granules is smooth and non-sticky, with better fluidity, which is convenient for transportation, storage, and spreading.
Working principle of the fertilizer granule coating machine
The fertilizer granule coating machine uniformly coats the surface of fertilizer granules with a layer of liquid film or powder film by physical or chemical means. Common coating materials include polymers, inorganic salts, vegetable oils or other environmentally friendly materials. Its workflow generally includes the following steps:
The fertilizer granules enter the drum or stirring chamber of the coating machine through the conveying device.
- Spraying coating material
The spraying system in the coating machine sprays the coating material evenly on the surface of the fertilizer granules.
The stirring system in the drum makes the fertilizer granules fully contact with the coating material during rotation, ensuring that each granule is evenly coated.
The coated fertilizer granules are discharged from the discharge port after cooling to form the final product.
The core value of the fertilizer granule coating machine lies in improving fertilizer utilization, extending fertilizer efficiency, reducing environmental pollution, and meeting the precise nutrient requirements of crop growth. For fertilizer companies, choosing a high-quality coating machine can not only improve product competitiveness but also bring more efficient production and greater market benefits to the company.
