Distinguished by its ambient-temperature, water-free, and high-efficiency characteristics, the roller press granulator production line stands as the preferred solution for the large-scale processing of urea fertilizer. It is specifically designed to accommodate urea’s inherent susceptibility to moisture absorption and its low melting point, enabling the standardized transformation of urea from powder to granules without the need for complex modifications—thereby balancing both processing efficiency and product quality.
The processing workflow is both simple and highly efficient: First, the powdered urea undergoes pretreatment to control its moisture content (keeping it ≤15%) and is milled to a uniform particle size, effectively preventing moisture absorption and subsequent caking. The material is then fed into a double roller press granulator, where it is formed under high-pressure rolling. This entire process is conducted at ambient temperature, thereby preventing urea decomposition and nutrient loss often associated with high heat, and eliminating the need for additional drying.
Following the forming stage, the granules are screened to remove any substandard particles, ensuring that the final product consists of uniform, compact granules that are ideal for storage and mechanized application. The production line offers flexible adjustability regarding rolling pressure and granule specifications, allowing it to adapt to urea processing requirements of varying scales without the need for additional specialized equipment.
Compared to traditional granulation methods, this production line requires no added water or binders; this fundamentally mitigates the risk of urea absorbing moisture, while simultaneously reducing energy consumption and production costs. Furthermore, it preserves the purity and fertilizer efficacy of the urea, ensuring a contamination-free product.
Tailored specifically for urea processing, this roller press granulator production line features user-friendly operation and exceptional adaptability. It effectively resolves critical pain points in urea processing—such as caking and nutrient loss—while simultaneously enabling the large-scale, standardized production of urea fertilizer.
