Both drum granulation and pan granulation use the wet granulation method. Pan granulators are ideal for producing small, uniform pellets. What’s more, you can use them in the production of animal feed, fertilizer, and other granulated products (you can also use the pan granulation production line to produce cat litter). Disk granulators are also relatively simple to operate and maintain. While drum granulators are best for producing larger pellets with a wider size distribution.
When choosing between a drum granulator and a disc granulator, many fertilizer manufacturers choose the former type because it provides higher throughput than the disc granulator. The drum granulator also has the advantage of being a closed system. This closed system ensures the granulation process in a closed environment, thereby limiting the dispersion of materials. However, workers should be at the scene to ensure the granulating process works smoothly.
The granulation effect of the rotary drum granulator will directly affect the granulating rate and product quality. It overcomes many disadvantages in the granulation process of the disc granulator, such as ingredient mixing, particle formation rate, particle strength, output, labor intensity, dust in the granulation workshop, and cost. It is excellent granulation equipment for the production of high-concentration compound fertilizers. The entire process of granulating is based on the physical movement of the materials inside the drum.
