Sulfur Coated Urea Fertilizer Machinery Supplier for Complete SCU Production Lines
Sulfur coated urea (SCU) has become an essential controlled-release fertilizer in modern agriculture. Manufacturers looking to improve nitrogen efficiency and reduce losses often seek a reliable sulfur coated urea fertilizer machinery supplier capable of providing complete production lines with consistent coating quality and long-term operational stability.
According to the International Fertilizer Association (IFA), controlled‑release fertilizer products such as sulfur‑coated urea are an important category of enhanced efficiency fertilizers that slowly release nutrients over weeks to months, helping improve nutrient use efficiency and reduce environmental losses in modern agriculture. The IFA 2019 Sustainability Report highlights sulfur‑coated fertilizers within the broader context of slow and controlled‑release fertilizer products.
A professional sulfur coated urea fertilizer machinery supplier ensures that every component, from the urea feeding system to the rotary coating drum, is optimized for high throughput and uniform coating.
What Is Sulfur Coated Urea Fertilizer Machinery
Sulfur coated urea fertilizer machinery refers to specialized equipment designed to apply a uniform sulfur layer to urea granules. The coating slows nitrogen release, enhancing crop nutrient uptake over time.
Definition of SCU Machinery
SCU machinery combines multiple units, including urea preheating, sulfur melting, spraying, drum coating, cooling, and screening. Each part must work in coordination to produce high-quality coated urea.
Why Specialized Machinery Is Essential
Ordinary fertilizer machines cannot handle molten sulfur properly. Only a certified sulfur coated urea fertilizer machinery supplier can provide systems that ensure consistent coating thickness, reduced waste, and long equipment lifespan.
Why Work With a Professional Machinery Supplier
Partnering with a professional supplier guarantees project success and reduces operational risks.
Experience and Project References
Suppliers with multiple installed SCU lines demonstrate proven process control and design expertise.
Technical Support and After-Sales Service
From commissioning to troubleshooting, ongoing support from a trusted sulfur coated urea fertilizer machinery supplier ensures long-term plant reliability.

7 Core Systems in SCU Fertilizer Machinery
A professional sulfur coated urea fertilizer machinery supplier typically offers the following seven core systems:
Urea Feeding and Preheating System
Ensures uniform granule flow and prepares material for coating.Sulfur Melting and Filtration System
Molten sulfur is filtered to avoid nozzle blockages.Precision Spraying Unit
Maintains correct coating ratios and uniform distribution.Rotary Coating Drum
Granules are rotated while sulfur is applied. Learn more about rotary coating machine solutions.Cooling and Solidification System
Stabilizes the coating layer quickly to prevent agglomeration.Screening and Recycling Section
Oversize and undersize particles are separated and returned to the system.Dust Collection and Control System
Ensures environmental compliance and safe operations.
Sulfur Coated Urea Production Process Explained
The process starts with screened and preheated urea granules. Molten sulfur is sprayed while granules rotate in the coating drum. The coated granules then pass through cooling, screening, and packaging systems.
For detailed procedures, manufacturers refer to a sulfur coated urea production process guide to optimize coating thickness and line efficiency.
Key Technical Parameters That Affect Coating Quality
Coating Temperature
Maintaining the proper sulfur temperature ensures optimal flow and adhesion.
Drum Residence Time
Granules must stay in the drum long enough for uniform coating but not too long to reduce throughput.
Spray Rate Control
Correct spray rate ensures the target coating percentage is achieved consistently.
Cooling Speed
Rapid cooling stabilizes granules and prevents sticking.
