As a commonly used nitrogen fertilizer, ammonium sulfate’s granulation process must address its characteristics of being easily hygroscopic, having a low melting point, and being prone to nutrient loss. The adaptability of the fertilizer granulator directly determines granulation efficiency and product quality. The double roller press granulator, due to its high compatibility with the material characteristics of ammonium sulfate, has become the best choice for granulating this material.
Room temperature extrusion molding. Ammonium sulfate easily decomposes when heated. The double roller press granulator does not require high-temperature heating; it only uses physical high-pressure extrusion to form ammonium sulfate powder, maintaining a constant room temperature throughout the process. This maximizes the retention of nitrogen nutrients, ensuring stable fertilizer efficacy.
Adaptability to hygroscopic properties. Ammonium sulfate is prone to caking and sticking to equipment after absorbing moisture. The extrusion roller surface of the fertilizer compaction machine is specially treated to prevent material adhesion, and the molding process does not require the addition of extra binders. It can directly process ammonium sulfate raw materials with moderate humidity, avoiding the impact of binders on fertilizer efficacy and reducing granulation failures caused by moisture absorption.
High efficiency, energy saving, and strong product adaptability. The press granulation technology has a simple process, forming granules from powder in one step without drying, significantly reducing energy consumption; the finished granules have high strength, uniform particle size, and are not prone to moisture absorption and caking, making them suitable for storage and mechanized fertilization.
In summary, the double roller press granulator precisely addresses the core pain points of ammonium sulfate granulation with its advantages of room-temperature molding, anti-sticking adaptability, and energy efficiency. This high degree of matching between “material characteristics and equipment function” makes it an irreplaceable choice for ammonium sulfate granulation, helping to produce high-quality ammonium sulfate granular fertilizer.
