The core advantages of organic fertilizer dry granualtors technology compared to wet granulation lie in three main dimensions: energy cost, production efficiency, and raw material compatibility. Furthermore, the absence of wastewater discharge aligns better with green production requirements. Specific advantages include:
1. No need for water/binders, eliminating subsequent drying and cooling processes, significantly reducing energy consumption. Overall production costs are more than 30% lower than wet granulation, saving on space and investment costs for drying equipment.
2. A simpler production process, with granulation in one step, resulting in higher production efficiency. For example, double roller press granualtors offer more stable single-unit capacity and eliminate the time-consuming drying process, enabling continuous batch production.
3. Wider raw material compatibility, capable of processing organic fertilizer raw materials with a moisture content of 8%-15%, without the need for significant pre-dehydration. It is particularly suitable for easily agglomerated or low-moisture raw materials such as distiller's grains, mushroom residue, and straw powder. It can also flexibly combine various organic materials for granulation.
4. No production wastewater and minimal dust (equipped with sealing devices), making environmental compliance easier. No wastewater treatment system is required, meeting the green production and environmental supervision requirements of the organic fertilizer industry, and simplifying operation and maintenance.
5. Finished granules have high hardness and good roundness, are less prone to moisture absorption and clumping, resulting in stronger storage and transportation stability. Nutrients are evenly distributed, preventing nutrient loss during drying.
6. Simpler equipment operation and maintenance. Without the complex maintenance of auxiliary equipment such as drying and cooling systems, there are fewer potential points of failure, lower labor and maintenance costs, making it suitable for rapid commissioning of small to medium-capacity organic fertilizer production lines.
