A Complete Guide to Wet Granulation Fertilizer Machines: Principles, Advantages and Selection Tips
In modern fertilizer production, granulation technology is the core link determining product quality, efficiency, and cost control. Among these, wet granulation fertilizer machine s have emerged as a popular choice for compound fertilizer, organic fertilizer, and blended fertilizer production, thanks to their high granulation rate, strong pellet strength, and uniform nutrient distribution. This article delves into the principles, types, applications, and selection criteria of wet granulation equipment, offering practical insights for industry professionals. What Is Wet Granulation? Wet granulation is a process that agglomerates powdered or fine-grained raw materials into regular pellets by adding liquid binders (e.g., water, urine, humic acid solution). The core mechanism relies on surface tension and adhesion from the liquid, forming "liquid bridges" between particles. Through mechanical pressing, rolling, or stirring, these bridges solidify into granules, which are then ...
