Double roller press granulator: Boosting organic fertilizer production for sustainable agriculture

As green farming concepts gain popularity, organic fertilizers are becoming a crucial support for modern agriculture. In organic fertilizer production, the double roller press granulator, as a core equipment, not only enhances production efficiency but also brings multiple benefits for sustainable agricultural development.

The double roller press granulator is an advanced physical granulation device. It works by using a pair of counter-rotating rollers to apply high-pressure extrusion on fermented organic materials at room temperature. This process forces the materials through mold holes on the roller surfaces, forming uniform-sized granules. Compared to traditional granulation methods, this dry process requires no heating or addition of binders, saving energy while maintaining organic fertilizer purity.

Granular organic fertilizers produced by this machine offer several agricultural advantages:

1. Improved Flowability  

Granular fertilizers flow easily, enabling mechanized and even application, which significantly boosts field operation efficiency. The granular form also reduces dust pollution during fertilization and minimizes losses during storage and transportation.

2. Slow, Long-Lasting Nutrient Release  

Granular organic fertilizers release nutrients gradually, matching crop growth needs. This slow-release feature prevents rapid nutrient loss, increases fertilizer utilization, and ensures balanced nutrition throughout the crop growth cycle for healthier development.

3. Enhanced Soil Structure

These granules continuously improve soil quality. As they decompose, they enrich soil organic matter and promote the formation of soil aggregates, strengthening water and nutrient retention. Long-term use boosts soil fertility and microbial diversity, creating a healthier environment for crops.

4. Environmental Benefits  

The granulator transforms agricultural waste into valuable fertilizer, reducing pollution through waste recycling. Widespread use of organic fertilizers also cuts reliance on chemical fertilizers, lowering risks of agricultural non-point source pollution and aligning with green farming principles.

With growing awareness of food safety and environmental protection, the double roller press granulator will play an increasingly vital role in organic fertilizer production, providing robust technical support for sustainable agriculture.
