Product Description
Introduction to the Complete Set of Urea Fertilizer Production Line
Our full set urea production line adopts advanced CO2 stripping urea synthesis technology, taking ammonia and carbon dioxide as raw materials to produce N46 high-purity granular/prilled urea fertilizer. The whole line includes synthesis system, concentration, prilling tower, granulation, coating, packaging, Automatic control unit. We offer customized annual output ranging from 5,000 tons to 500,000 tons. With PLC intelligent control, it features low energy consumption and stable operation. We provide full after-sales service including overseas installation. It is widely used in large chemical fertilizer factories all over the world.
1. Product Overview
Urea production line is a complete chemical equipment for producing agricultural nitrogen fertilizer urea (carbamide, CO(NH2)2, nitrogen content ≥46%). The whole process covers raw material reaction, urea solution concentration, prilling/granulation, anti-caking coating, automatic weighing and packaging.
We provide two mainstream technical routes:
- CO2 stripping large-scale urea plant (annual output 50,000-500,000 tons, for large chemical groups)
- Small & medium urea granulation line (1-30 tons/day, for regional fertilizer factories, compound fertilizer supporting production)
Optional extended line: sulfur coated slow-release urea production system, AdBlue automotive urea liquid production line.
2. Core Production Process Flow
Raw Material (NH3+ CO2) → Urea Synthesis Reactor → Medium Pressure Recovery → Urea Solution Concentration → Prilling Tower / Rotary Granulator → Cooling Screening → Anti-Caking Coating → Automatic Packaging → Finished Urea Storage
Finished product: White granular urea 2-4mm / prilled urea 0.8-2.8mm, biuret ≤0.9%, moisture ≤0.5%, meet international fertilizer export standards.
3. Main Equipment Composition
- Urea Synthesis & Reaction Unit: High-pressure reactor, condenser, separator
- Concentration & Evaporation System: Multi-effect evaporator, vacuum pump
- Molding Unit: Prilling tower / rotary drum granulator, roller extrusion granulator
