The double roller press granulator production technology boasts significant advantages, characterized by dry, room-temperature operation, low energy consumption, high efficiency, high-quality granules, and environmental safety. It is the preferred solution for large-scale production of compound fertilizers, organic fertilizers, and blended fertilizers.
This process utilizes dry granulation, relying on double-roller high-pressure direct molding at room temperature. It eliminates the need for drying, cooling, steam, and other auxiliary equipment, resulting in a shorter process flow, smaller footprint, lower investment, and significantly reduced energy consumption compared to wet granulation, leading to a substantial decrease in operating costs. Production is convenient to start and stop, and formula switching is flexible, adaptable to multiple product categories and small-batch production. Fine powder can be recycled for regranulation, achieving near 100% raw material utilization, eliminating waste and increasing efficiency.
The granules produced have high density, high hardness, are not loose, do not return to powder form, have uniform and regular particle shape, stable strength, and are not prone to moisture absorption and clumping. This facilitates storage, transportation, and blending with BB fertilizers, resulting in a more stable fertilizer release.
The entire process operates in a closed system with negative pressure dust removal, resulting in no wastewater or exhaust gas emissions. Dust is easily collected and treated, meeting environmental protection and safety production requirements. The equipment features a compact structure, simple operation, stable performance, low failure rate, convenient maintenance, and long service life. It boasts strong process adaptability, capable of producing various products such as NPK compound fertilizer, organic fertilizer, inorganic salts, and slow-release fertilizer. Granule specifications can be quickly switched by adjusting the roller gap and pressure to meet diverse market demands. Its overall cost-effectiveness and market competitiveness are outstanding.
