Furuixue Anti-Caking Oil & Powder Solution for High Tower NPK Granulation

Professional combined application of Furuixue anti-caking oil and powder for high tower compound fertilizer. Suitable for urea-based, chloride-based, sulfate-based and nitrate-based NPK, stable anti-caking performance for ocean transportation and long-term storage.

Many compound fertilizer manufacturers struggle with caking issues during long-term stacking, high-temperature and high-humidity storage, and ocean transportation. Using anti-caking oil or powder alone cannot meet the strict anti-caking standards for export fertilizers. Targeting mainstream high-tower granulation production lines, Furuixue has developed a mature combined anti-caking solution with matched oil and powder agents. The dual-protection and synergistic effect thoroughly solves granule caking problems during storage and transportation, fully adapting to scenarios of foreign trade export and long-term fertilizer stacking.

On-Site Technical Process

After granulation, cooling and screening, qualified compound fertilizer granules are evenly delivered to the coating roller for surface protection treatment.

First, Furuixue anti-caking oil is evenly sprayed at the front section of the coating roller with a controlled dosage of 1.5–2.2kg per ton of fertilizer. As the granules roll and rub continuously inside the roller, the anti-caking oil fully covers the granule surface and forms a dense, water-repellent protective oil film.

Subsequently, Furuixue anti-caking powder is added at the middle section of the coating roller. The powder stably adheres to the oil film on the granule surface, forming a dual-layer protection structure combining oil film and physical powder isolation.

This segmented feeding process effectively avoids common defects of traditional single-point spraying and feeding, such as uneven coating, missing coverage and local agent accumulation. It ensures comprehensive protection for every fertilizer granule and delivers more stable and long-lasting anti-caking performance.

Anti-Caking Mechanism of Oil and Powder Synergy

The water-repellent oil film formed by anti-caking oil effectively isolates external moisture and humidity, prevents the formation of crystal bridges on granule surfaces, and eliminates the core causes of fertilizer caking from the source.

The matched anti-caking powder forms a physical isolation layer on granule surfaces, greatly reducing direct contact and adhesion between fertilizer particles.

The synergistic effect of oil and powder dual protection perfectly adapts to harsh working conditions including high temperature, high humidity, long-distance ocean transportation and long-term stacking, significantly reducing the storage and transportation loss of compound fertilizers.

Applicable Fertilizer Types and Customization Advantages

This process is suitable for urea-based, chloride-based, sulfate-based and nitrate-based compound fertilizers. The agent formula and dosage ratio can be flexibly adjusted according to customers’ fertilizer formulas, raw material ratios and production line conditions. It delivers strong adaptability for fertilizers with any urea content or urea-free formulas to provide exclusive anti-caking solutions.

Primarily designed for high-tower granulation production lines, the solution can also adapt to drum granulation and other mainstream production equipment by adjusting process parameters on site. In addition, Furuixue anti-caking oil supports color customization, helping manufacturers distinguish fertilizer grades and realize convenient finished product classification management.

Core On-Site Application Advantages

1. Dual-protection synergistic effect: The combined use of oil and powder agents provides far better anti-caking performance than single agents, ensuring long-term stability and meeting strict requirements for export ocean transportation.

2. Uniform and full coating: The segmented feeding process avoids missing spraying and agent accumulation, achieving uniform granule coating and better finished product appearance.

3. Wide application range: Compatible with all mainstream compound fertilizers including urea-based, chloride-based, sulfate-based and nitrate-based types, with personalized formula adjustment support.

4. Simple and convenient construction: No modification to original coating roller equipment is required, which is directly applicable to existing production lines with low implementation costs.

5. Customized service: Support exclusive customization of agent formulas, dosage and product colors to fit actual production needs of manufacturers.
