The answer is yes. Fertilizer extrusion granulation technology, with its controllable mechanical pressure and precise molding control, effectively addresses the problems of loose and unevenly sized bio-fertilizer granules. It is well-suited to the characteristics of bio-fertilizers containing microbial agents and complex nutrients, making it a high-quality granulation solution that balances granule quality and biological activity.
This technology ensures granule uniformity through pre-treatment and pressure control. After crushing, screening, and uniform mixing of raw materials, the mixture is fed into a fertilizer granules compaction machine. The granules are tightly bound together through roller or screw extrusion, and the particle size can be precisely controlled through equipment parameters, avoiding size variations.
The increased granule strength stems from the densification achieved during extrusion molding. The gaps between raw materials are compressed, enhancing compressive strength and reducing breakage and clumping during storage and transportation, while also preventing the loss of microbial agents. Compared to other technologies, it does not require high-temperature drying, thus protecting the survival of heat-sensitive microorganisms, balancing both strength and biological activity.
Two points need to be controlled during operation: firstly, the raw material moisture content should be controlled at 5%-8% to avoid sticking or poor molding; secondly, the extrusion pressure should be precisely controlled to suit different formulations, preventing improper pressure from damaging microorganisms or leading to loose granules.
In summary, fertilizer extrusion granulation technology can significantly improve the strength and uniformity of bio-fertilizer granules, adapting to their characteristics. It optimizes product appearance and storage stability while preserving biological activity, making it suitable for large-scale production and field application.
