As a commonly used nitrogen fertilizer, ammonium sulfate requires a granulation process that accommodates its characteristics of being easily hygroscopic, heat-sensitive, and having moderate viscosity. The roller press granulator production line, with its targeted process design, has become the best choice for balancing quality and efficiency, meeting the needs of large-scale granulation.
Cold pressing is suitable for the heat-sensitive nature of ammonium sulfate, avoiding nutrient loss. The double roller press granulator does not require high-temperature drying; it directly forms granules through high mechanical pressure, avoiding nutrient decomposition and volatilization caused by high temperatures, thus maximizing fertilizer efficiency and matching its heat-sensitive characteristics.
No large amount of binder is needed, meeting the molding requirements. Ammonium sulfate itself has a certain viscosity, and roller press granulation can complete the molding process relying on the viscosity of the raw materials, eliminating the need for additional binders. This reduces costs and avoids the introduction of impurities, ensuring the purity and stable fertilizer efficiency of the granules.
Stable molding, suitable for large-scale production. The particle size and strength can be precisely controlled, solving the problems of easy caking and uneven molding of ammonium sulfate. The granules have good fluidity, facilitating storage, transportation, and application. The roller press granulator production line has a high degree of automation and can operate continuously, adapting to diverse production capacities and improving granulation efficiency.
Environmentally friendly and energy-saving, consistent with green production. There is no wastewater or exhaust gas discharge during production, and energy consumption is far lower than wet granulation. Unqualified granules can be recycled, reducing raw material waste and balancing environmental protection and resource utilization, meeting the diverse needs of ammonium sulfate granulation.
