Granule Coating: The Invisible Armor for Extended NPK Fertilizer Effect
What is the core value of compound fertilizer granule coating equipment? Compound fertilizer granule coating equipment refers to a specialized mechanical system that sprays a layer of functional material onto the surface of NPK fertilizer granules. By adjusting the thickness, porosity, and degradation rate of the coating, the nutrient release rate is artificially controlled. The core value of coating equipment lies in converting fast-acting fertilizers into slow-release or controlled-release products, extending the fertilizer effect period from 15-30 days to 60-120 days, increasing nutrient utilization from 30%-50% to 60%-80%, while reducing leaching losses and environmental pollution.
