Is a coating machine dispensable in a fertilizer production line?
In fertilizer production lines, coating machine s are far from being optional accessories. Rather, they are core devices that improve product quality and expand application scenarios. Their functionality is irreplaceable in modern fertilizer production. From the perspective of optimizing fertilizer performance, coating machines play a crucial role in precisely controlling nutrient release. By evenly spraying coating materials such as sulfur and resin onto the surface of granular fertilizer, a film with controlled air permeability is formed, allowing nutrients such as nitrogen, phosphorus, and potassium to be slowly released according to the crop's growth cycle. This slow-release effect avoids the risk of seedling burn associated with traditional fertilizers, reduces fertilization frequency, and is particularly suitable for crops with long growing periods, such as fruit trees and flowers. Without the film coating process, fertilizers are prone to rapid dissolution, leading to nutrie...
