Common organic fertilizer granulator machine include: roller extrusion granulator, drum granulator, disc granulator machine, new organic fertilizer granulator, new two-in-one organic fertilizer granulator, flat die granulator machine, ring die granulator, each granulator has its own production characteristics, and the fertilizer granulator machine price varies. Let's learn about the drum granulator today.
1. What types of materials can the drum granulator process?
Generally speaking, a drum granulator can process any bulk solid into a dry fine powder. This flexibility is ideal for many industries, processing everything from specialty chemicals and fertilizers to minerals and ores and everything in between.
2. What are the advantages of drum granulator compared with disc granulator?
When choosing between a drum granulator and a pan granulator, the drum is usually chosen because it offers higher throughput than the pan granulator. The drum also has the advantage of being a "closed" system, meaning that the granulation takes place in a closed environment, so that outward dispersion of material is limited.
3. Is the drum granulator batch or continuous?
Drum granulators are typically used in continuous settings, but in some organic fertilizer production environments they may be used as batch equipment.
4. What is the residence time of the drum granulator?
Retention time is a process parameter used to control the identity and quality of the material leaving the drum, so it can vary widely depending on process and product goals. Typically, the residence time in the granulator may be between 30 seconds and 60 minutes.
5. Does the product leaving the granulator need to be dried?
Since the granulation process relies on a liquid binder to form and layer the granules, the product leaving the granulator is wet and must be dried, usually in a rotary dryer, which due to the tumbling action that occurs as the drum rotates The dryer further rounds and "polishes" the particles.
