A Resin Fertilizer Coating Production Line
Resin Fertilizer Coating Production Line is an industrial system that coats fertilizer granules with resin materials (e.g., polyurethane, acrylic resin) to form a uniform film, ultimately producing
slow-release or controlled-release fertilizers that regulate nutrient release.
Its key role is to solve the problem of rapid nutrient loss from traditional fertilizers. By wrapping fertilizer granules in a resin film, it controls the rate of nutrient release (from 1 to 12 months) to match the nutrient needs of crops throughout their growth cycle.
The production follows 4 key continuous steps, with high automation:
- Pretreatment: Screen and dry fertilizer granules (to 1-3% moisture) to ensure uniform flow.
- Coating: In a drum or fluidized-bed coater, atomize and spray resin solution onto the surface of dispersed granules to form an initial film.
- Curing: Heat (60-120℃) or use UV light to harden the resin film into a dense, water-resistant layer.
- Post-treatment: Cool, re-screen (remove lumps), and package the finished product.
Only the most critical equipment is included (to avoid complexity):
- Coating Machine: The core device for granule dispersion and resin spraying (drum type for large capacity, fluidized-bed type for precise coating).
- Resin Preparation System: Mixes resin, solvents, and curing agents in accurate proportions.
- Curing System: Heats or irradiates to solidify the resin film.
- Automatic Control System: Uses PLC to adjust temperature, spray volume, and rotation speed for stable production.
- Higher Fertilizer Efficiency: Reduces nutrient loss, increasing fertilizer utilization by 30-50%.
- Stable Performance: The resin film is water-resistant and wear-resistant, allowing 12+ months of storage without caking.
- Eco-Friendly: Lowers nitrogen loss by over 40%, reducing soil and water pollution.
- High Efficiency: A single line can produce 50,000-500,000 tons/year, with only 2-3 workers per shift.
