Core Equipment & Industry-Specific Features
Our CRF production equipment is a modular system integrating key functional units, with targeted designs to solve pain points like uneven coating, coating shedding, and unstable release periods:
Application Scenarios
Our equipment covers production of mainstream CRF types, adapting to different crop nutrient demand cycles:
1. Sulfur-Coated Controlled-Release Fertilizer (Low-Cost, Suitable for Field Crops)
- Equipment Configuration: Sulfur melting tank + fluidized bed coating machine + air-cooling shaping machine;
- Application: For wheat, corn, rice (3-6 months release period)—coating thickness 30-50μm, nutrient release rate ≤15% in the first month;
- Case: A 10,000-ton/year CRF plant in Henan used this line—sulfur coating uniformity reached 97%, crop yield increased by 12% vs. conventional fertilizer, fertilizer use reduced by 18%.
2. Resin-Coated Controlled-Release Fertilizer (Long Release Period, Suitable for Cash Crops)
- Equipment Configuration: Resin-curing agent mixing system + low-temperature fluidized bed coating machine + water-cooled shaping machine + VOC treatment module;
- Application: For fruit trees (apple, citrus), greenhouse vegetables (tomato, cucumber) (6-12 months release period)—coating thickness 50-100μm, nutrient release rate ≤10% in the first month;
- Case: A 30,000-ton/year CRF plant in Shandong produced resin-coated fertilizer for citrus—release period stabilized at 8 months, citrus sugar content increased by 1.5 Brix, reducing topdressing times from 4 to 1.
3. Biodegradable-Coated Controlled-Release Fertilizer (Eco-Friendly, Suitable for Organic Agriculture)
- Equipment Configuration: Ultrasonic atomization coating machine + cold air shaping machine + biodegradable material mixing tank;
- Application: For organic vegetables, tea, Chinese herbs (3-6 months release period)—coating material (starch-polyvinyl alcohol composite) fully degrades in soil within 12 months, no environmental pollution;
- Case: A European organic CRF enterprise used this line—biodegradable coating pass EU ECOCERT certification, product exported to 12 EU countries, market share increased by 20%.
4. Customized CRF Production (Crop-Specific Formulas)
- Equipment Adaptability: Supports mixing of coated and uncoated granules (e.g., 70% resin-coated NPK + 30% quick-release urea) to meet “slow-release + quick-supply” nutrient demand of crops like cotton, sugarcane;
- Case: A Brazilian sugarcane CRF plant customized a production line—coated granules (8 months release) mixed with quick-release potassium, sugarcane yield increased by 15%, sucrose content improved by 0.8%.
Pricing System
Adopt “modular configuration + factory direct supply” with no middlemen, cutting procurement costs by 20%-35% vs.
Why Choose Us for CRF Production Equipment?
As a supplier specialized in CRF equipment, we provide solutions beyond machinery—focused on helping customers achieve stable production and market competitiveness:
Deep Industry Expertise
- R&D Strength: 12-person R&D team (10+ years in CRF equipment development), holding 15 national patents (e.g., “Ultrasonic Atomization Biodegradable Coating Machine”, “Precision Sulfur Coating System”); cooperates with China Agricultural University to optimize coating parameters for different crops’ nutrient demand.
- Material Adaptation: Has tested 20+ coating materials (sulfur, polyurethane, starch-based polymers) and established a “material-equipment parameter database”—can quickly match equipment settings to customer’s coating material, avoiding trial-and-error costs.
Tailored Customization
- Demand-Oriented Design: Adjusts equipment structure based on CRF type (release period, coating material) and production scale—e.g., adding heat insulation layers for sulfur coating lines in cold regions, or increasing nozzle quantity for high-yield resin coating lines;
- Post-Commissioning Support: Sends CRF technology engineers to guide on-site formula debugging, ensuring the first batch of products meets GB/T 23348 standards (release period error ≤10%).
Proven Success Cases
- Domestic: A leading CRF enterprise in China used our 50,000-ton/year resin coating line—production efficiency reached 2.5 tons/hour, product qualification rate (release period compliance) increased from 85% to 99%, annual revenue increased by $3 million;
- Overseas: A U.S. CRF company adopted our biodegradable coating line—passed EPA organic certification, product was listed by Walmart’s garden department, sales volume doubled in 1 year;
- Pilot Project: A Kenyan agricultural research institute used our small-scale pilot line—developed local sulfur-coated CRF for maize, reducing fertilizer import dependence by 30%.
