The coating machine melts the coating material in the heating tank and then sprays it onto the fertilizer.
With “solving fertilizer coating pain points, ensuring uniform coating & functional stability” as the core goal, our fertilizer coaters integrate targeted technologies:
For irregular organic fertilizer granules (manure/straw-based): Adopt “rotary drum + multi-point spray” design, with adjustable drum speed (10-30 rpm) and spray pressure (0.3-0.8 MPa), ensuring coating coverage ≥98% and thickness variation ≤0.1mm;For regular chemical fertilizer granules (urea/ammonia phosphate): Use “fluidized bed + air-blowing coating” technology, creating a stable air cushion to suspend granules, avoiding collision damage and realizing 360° uniform coating.
Compatible with all fertilizer coating materials—water-based anti-caking agents (for organic fertilizer), solvent-based slow-release resins (for compound fertilizer), and liquid microbial agents (for biological fertilizer);Equipped with temperature-controlled material tanks (5-60℃ adjustable) to maintain coating material fluidity (critical for high-viscosity resins), avoiding clogging.
Add “post-coating hot air curing” module (temperature 40-80℃) to enhance coating adhesion—after testing, coating shedding rate is ≤2% during transportation (vs. 8%-12% for ordinary coaters);For abrasive fertilizer granules (e.g., mineral-based fertilizer), the coater inner wall is lined with wear-resistant polyurethane (HRC 65+), extending service life to 7-9 years.
Our fertilizer coaters cover all coating links of fertilizer production lines, targeting different fertilizer types:
Mini rotary coaters (capacity 0.5-2 tons/hour) for small organic fertilizer workshops;Continuous fluidized bed coaters (capacity 5-20 tons/hour) for large compound fertilizer plants with 24/7 production needs.
Adopt “factory direct supply + fertilizer line customization” with no middlemen, cutting procurement costs by 18%-28% vs.
As a coater supplier specialized in fertilizer industry, we provide solutions tailored to fertilizer production needs:
A 30,000-ton/year organic fertilizer plant in China reduced storage caking rate from 38% to 4% with our rotary coater, cutting inventory loss by 25%;
A Brazilian compound fertilizer plant extended nutrient release period to 5 months with our fluidized bed coater, increasing product market price by 18%;
A U.S. microbial fertilizer enterprise retained 96% of viable bacteria with our low-temperature coater, passing EPA organic product certification.
Whether you need to solve organic fertilizer caking, improve chemical fertilizer slow-release effect, or add nutrients to special fertilizer, we provide coaters that match your production line.
