Sulfur coated urea production line

Sulfur coated urea production line Introduction

Sulfur coated urea, as an efficient slow-release fertilizer, plays an important role in modern agricultural production due to its unique slow-release properties, comprehensive nutrient supply, wide adaptability, and environmental safety. The sulfur coated urea production line includes raw material preparation, urea granulation, sulfur melting, sulfur coating, drying treatment, screening and grading, packaging and storage, covering multiple links from raw material preparation to final product packaging and storage.

Main Technical Parameters

Based on different processes and equipment, we can customize a sulfur coated urea production line with an annual output of 10000 to 500000 tons for you.

Production process
Urea granulation: Urea raw materials are formed into urea particles under certain conditions using disc granulators, conversion granulators, or spray granulators based on the characteristics of the raw materials.
Sulfur smelting: Sulfur is first melted in a smelting furnace to form commercial sulfur, which is convenient for subsequent urea particle coating.
Coating treatment: In the coating machine, molten sulfur is wrapped around the preheated urea surface, tightly bonded to form a microcrystalline polymer coating layer.
Cooling solidification: The coated urea particles are cooled by a cooling machine to ensure the stability of the urea particles
Screening treatment: To ensure uniform particle size, particle screening is carried out. Qualified particles are classified as finished particles, while unqualified particles can be further crushed and granulated.
Packaging and storage: Finished urea granules are packaged and stored using an automatic packaging machine.
