Fertilizer coating machines are key equipment for upgrading finished products in organic fertilizer, compound fertilizer, and slow-release fertilizer production lines. Their core function is to uniformly coat the surface of fertilizer granules with a protective film, which enhances granule hardness and enables slow nutrient release.

The equipment is based on a rotating coating cylinder and an atomizing spray system. During operation, cooled fertilizer granules enter the inclined coating cylinder, and the atomizing spray system precisely sprays the coating agent onto the granule surface, ensuring that each granule is fully coated.

Product Features:

Superior Coating Effect: Atomized spraying + rotating drum tumbling achieves a coating uniformity rate exceeding 95%, forming a uniform protective film of 0.05-0.2mm, enhancing granule hardness, reducing transportation losses from 8% to 2%, and also making the fertilizer appearance smoother.

High Functional Value: Enables slow nutrient release, such as extending the release period of slow-release fertilizer from 30 days to 90 days, avoiding “seedling burn” and nutrient loss; the shelf life of organic fertilizer is extended to 18 months after coating, increasing product added value.

Wide adaptability: Adjustable spray volume and cylinder speed; adaptable to different particle sizes from 1-8mm; compatible with various coating agents such as paraffin, resin, and humic acid; meets the needs of different fertilizer types including organic fertilizer, compound fertilizer, and slow-release fertilizer.
