As one of the mainstream equipment of NPK fertilizer production line, compound fertilizer equipment must have its advantages. Because the compound fertilizer equipment can produce a variety of fertilizers, especially the coated fertilizer used in the current market. Coated fertilizer was boldly conceived as early as the beginning of last century. Through efforts, it finally realized and entered the era of coated fertilizer.

Advantages of coated fertilizer:

1. It can reduce the loss of fertilizer nutrients and significantly improve the utilization rate of fertilizer;
2. Avoid excessive fertilization and soil hardening of dry crops.;
3. Prevent the accumulation of nitrate in soil, pollute the environment and even poison human and livestock due to large amount of nitrogen fertilizer;

4. It can coordinate crop nutrient supply, implement balanced fertilization and achieve high quality and high yield;
5. Reduce the times of fertilization and save labor and time;
6. It is suitable for mechanized fertilization and can greatly improve the work efficiency of large-scale fertilization.

Selection principles of coating materials

Coating material is the material basis to ensure the function of coated fertilizer. In order to ensure the expected effect of coating fertilizer, the selected coating material must meet the following requirements.

1. Adhesion. After surface treatment, the granular fertilizer contacts with the powder of the coating material in the disc granulation equipment to make the coating material adhere to the fertilizer surface evenly, and finally seal the surface with a covering agent.
2. Spraying. The coating material is melted and sprayed on the fertilizer in a disc fertilizer granulator or drum fertilizer granulator, and then treated with an appropriate treatment agent.
3. Put the fertilizer to be coated together with the coating material into the fluidized bed and fully mix to form uniform particle coated fertilizer.
The above is the material selection requirements of coated fertilizer produced by compound fertilizer equipment and the advantages of coated fertilizer. Moreover, the production of this coated fertilizer is relatively simple compared with other fertilizers, and it is also the choice of fertilizer manufacturers who have just entered this industry.
