A Urea Melting Granulation Production Line is a specialized industrial system for producing granular urea fertilizer by melting urea raw materials and shaping them into uniform particles.

Urea Melting Granulation Production Line Core Definition

It is a continuous production line that converts solid urea (prills or crystals) into molten state through heating, then forms granular products via granulation equipment, and finally completes cooling, screening and packaging. It is the mainstream production technology for high-quality granular urea.

Urea Melting Granulation Production Line Key Components and Working Process

Melting System: Urea is heated to 132-138°C (melting point of urea) in a melter, with temperature control to avoid decomposition.

Granulation Unit: Molten urea is sprayed into a granulator (common types include spray granulator, fluidized bed granulator) through nozzles.

Solidification & Cooling: Droplets of molten urea cool and solidify into spherical or irregular granular forms in the granulator, then enter a cooler for further temperature reduction.

Screening & Classification: Granules are sorted by size through a vibrating screen, with unqualified particles (too large/small) crushed and recycled to the melting system.

Packaging System: Qualified granular urea is conveyed to a packaging machine for weighing and bagging, ready for storage or transportation.

Urea Melting Granulation Production Line Main Features

High product quality: Granules have uniform particle size, high strength and good fluidity, suitable for mechanized fertilization.

Continuous production: The whole line operates continuously with high production efficiency and stable output.

Good environmental performance: Closed-loop design reduces dust emission, and tail gas is treated to meet environmental standards.

Flexible configuration: Can adjust granule size and production capacity according to market demand.

Urea Melting Granulation Production Line Application Scope

Mainly used in large and medium-sized chemical fertilizer plants for producing granular urea fertilizer. The product is widely applied in agricultural production (grain crops, cash crops, fruits and vegetables) as a high-nitrogen fertilizer, and also used in industrial fields such as feed additives and chemical raw materials.

Urea Melting Granulation Production Line development trend

Technical route optimization: parallel high tower/spraying/fluidized bed melting granulation, focusing on nozzle, temperature control, tail gas treatment, and urea control; The proportion of integrated granulation of molten phosphorus and potassium has increased.
Intelligence and automation: online particle size/strength detection, closed-loop temperature control, energy consumption dashboard, remote operation and maintenance, reducing manual labor and fluctuations.
Energy conservation and environmental protection: waste heat recovery, tail gas washing/denitrification, dust recovery, reducing emissions and energy consumption; Popularization of low nitrogen combustion and insulation design.
Product diversification: slow-release/coated urea, urea based compound fertilizer, industrial grade special particles, enhancing added value and market competitiveness.
Region and Competition: Chinese equipment and engineering companies are accelerating their overseas expansion, seizing EPC and renovation orders in Southeast Asia/South Asia; Top enterprises integrate upstream and downstream, providing integrated solutions.
