Fertilizer manufactured with qualified and compliant Fertilizer Granulation Additive will not become sticky at all if the material is applied at the standard mixing ratio and produced following standardized processes. Instead, the additive effectively solves common manufacturing pain points including sticky fertilizer, equipment adhesion and particle agglomeration in traditional granulation processes. It serves as a core auxiliary material to optimize particle conditions and improve finished fertilizer quality. Qualified granulation additives available on the market consist of functional lubricating, dispersing and moisture-proof components. They contain no high-viscosity colloid, grease or other substances that leave adhesive residues. Their working principle is to evenly coat powdered fertilizer raw materials and form a thin, dry protective film on powder surfaces. This film offsets intermolecular adhesive forces of raw materials to prevent powder agglomeration during granulation. It also blocks water vapor from the air and reduces moisture-induced stickiness of fertilizer particles, fundamentally ensuring dry and loose fertilizer particles.
Sticky fertilizer encountered in practical production is not caused by the additive itself, but by secondary problems stemming from improper operation and process control. There are three main scenarios. First, excessive additive dosage. Each fertilizer type has a standard dosage range, generally 0.2% to 0.5% of the total raw material weight. Blindly increasing the dosage leads to uneven fusion of surplus additive, leaving residues on fertilizer particle surfaces and creating slight stickiness. Second, inadequate drying in production. Moderate water supports particle formation during granulation. Insufficient drying temperature or short drying time leaves free moisture inside and on particle surfaces. Even with additive addition, fertilizer still absorbs moisture and turns sticky. Third, excessive moisture in raw materials. If nitrogen, phosphorus, potassium feedstock or organic fertilizer base material carries moisture beyond the process adaptation range, the dispersing and moisture-proof effects of the additive will be weakened and cannot counteract stickiness brought by high humidity.
Besides, improper additive selection may also trigger stickiness. Different fertilizer types match different additive formulations. Formulations for organic fertilizer, compound fertilizer and water-soluble fertilizer differ greatly. If additives designed for high-viscosity granulation are mistakenly used in ordinary granular fertilizer production, finished products will show surface stickiness. On the contrary, with matched additive type, accurate dosage and standardized processes, Fertilizer Granulation Additive only improves particle forming performance. It delivers uniform particle size and a dry surface. The fertilizer remains non-sticky and prevents caking and hardening during long-term storage, improving convenience for warehousing and application. Particles stay loose without adhesion during manual spreading and mechanical broadcasting. It effectively avoids uneven fertilization and fertilizer machine blockage, adapting to various fertilization scenarios.
