In farming, traditional powdered or low-strength granular fertilizers easily lose nutrients due to rain washing them away, evaporation, or microbial breakdown. This lowers their effectiveness. Double roller press granulators use high-pressure physical shaping to significantly improve fertilizer granule stability and slow-release properties. This reduces nutrient loss and increases fertilizer efficiency.

1.Slows Dissolution

Compacted fertilizer granules have a dense structure. They release nutrients slowly when wet, reducing fast dissolution and loss from rain.

Compared to disc granulators or rotary drum granulators, pressed granules are more durable during storage and transport, meaning less powder waste from breakage.

2.Reduces Evaporation Loss

Fertilizers like urea and ammonium nitrogen easily evaporate when powdered. Pressing them into granules creates a sealed structure, reducing ammonia gas loss and improving nitrogen use.

3.Lessens Microbial Breakdown Impact

Organic matter in compost or compound fertilizers breaks down quickly outdoors due to microbes. Pressed granules are denser, slowing down microbial action and extending fertilizer release.

4.Works Well with Coating Tech

Pressed granules have a smooth surface. This makes them ideal for later coating (like sulfur or polymer coatings), further enhancing slow-release and reducing nutrient loss.

In short, double roller press granulators significantly boost fertilizer efficiency. For making compound fertilizers, organic fertilizers, and specialty fertilizers, this technology is a practical solution to lower farming costs and improve fertilizer performance.
