Rotating drum combining granulation and drying for producing uniform granules
Efficient granulation and drying are necessary to producing consistent fertilizer granules; our rotary drum spray dryer granulator is designed to combine these processes. By atomizing raw material slurry and spraying it onto a bed of recycled materials, the granulating machine integrates granulation, drying, and screening in one continuous process. Key components include the main and auxiliary drive systems, the drum body, knocking device, support roller system, sealing system, feed/discharge boxes, and the atomizer, all working together to ensure smooth operation and high-quality output.
Granular Fertilizers
Features
- Tooth-shaped lifting flights inside the drum help form a uniform material curtain. The slurry is sprayed through pneumatic nozzles, evenly coating fine particles within the drum. As the material moves through the drum, heated air from the furnace ensures efficient drying, creating solid and uniform granules.
- Larger particles are crushed and returned to the beginning of the process for re-granulation, while fine particles are recycled back through an internal system, optimizing the efficiency of the overall granulation and drying operation.
