In organic fertilizer production,the disc granulator is the core equipment determining product quality. A good granulation process not only boosts granule strength but also significantly increases output.
1.Raw Material Pre-treatment
Control material fineness (80-120 mesh is best) and ensure thorough mixing.
Adjust moisture to the optimal range. Add binders when necessary to enhance bonding strength.
2.Optimizing Process Parameters
Adjust the disc tilt angle (45°-60°) to extend pellet formation time and increase density.
Optimize rotation speed based on material properties to ensure even rolling and uniform granules.
Precisely control spray liquid volume. Use atomizing nozzles for even liquid distribution.

3.Equipment Maintenance and Upgrades
Regularly check the disc granulator for wear and maintain appropriate surface roughness.
Adjust the scraper position to prevent material buildup or uneven rolling.
For high hardness needs, use granulators with a pre-compression function to increase granule density.
4.Environmental Control
Use a “dual-zone management” approach in the workshop: Control granulation zone humidity at 60-70% and drying zone humidity at 40-50%.
Implement a “slow drying process” for post-treatment: Use gradual heating from 40-60°C, keeping drying time to 20-30 minutes.
Use a dual-stage classification system for the final product to ensure uniform hardness.
In summary, optimizing the raw material mix, adjusting process parameters, and maintaining equipment can significantly enhance disc granulator granule hardness, improving product quality and market competitiveness.
