Characteristics and Advantages of Disc Granulator Process
The disc granulator is a common granulation device in NPK blending fertilizer production lines. It works by using a tilted, rotating disc to roll materials into balls under centrifugal force. This process offers these key advantages:
1.Lower investment cost: Simple equipment structure means a smaller initial investment, ideal for small to medium fertilizer plants.
2.Intuitive operation: Easy to adjust process parameters with high visibility for management.
3.Lower energy consumption:Consumes less electricity compared to drum granulators.
4.Simpler maintenance: Less complex mechanical structure reduces daily upkeep.
Core Advantages of Rotary Drum Granulator Process
The rotary drum granulator uses a rotating drum to form granules inside the cylinder. It excels in NPK blended fertilizer production:
1.High capacity: Suited for large-scale continuous production; typically higher single-machine output than disc granulators.
2.Uniform granules: Produces rounded particles with a tight size distribution.
3.Strong process adaptability: Handles high-moisture materials well and suits various NPK fertilizer formulations.
4.High automation: Easily integrated with downstream processes like drying and cooling.
Selection Recommendations
For small to medium NPK blending plants, especially those producing many product types in smaller batches, the disc granulator is a cost-effective choice. Large compound fertilizer producers prioritizing high, stable output and product consistency will find the drum granulator more advantageous.
Of course,actual selection should also consider raw material properties, product positioning, and plant conditions.
