Based on aggregated insights from multiple verified factory profiles within the CNFX directory, the standard Rotary Granulation Drum used in the Chemical Manufacturing sector typically supports operational capacities ranging from standard industrial configurations to heavy-duty production requirements.
A canonical Rotary Granulation Drum is characterized by the integration of Drum Shell and Internal Lifters (Fights). In industrial production environments, manufacturers listed on CNFX commonly emphasize Carbon Steel (Shell) construction to support stable, high-cycle operation across diverse manufacturing scenarios.
A rotating cylindrical vessel where urea melt is sprayed onto seed particles and solidified into granules through cooling and tumbling action.

The drum features a carbon steel shell for structural integrity, stainless steel internal lifters and spray system for corrosion resistance, and an abrasion-resistant lining to withstand continuous tumbling action during urea granulation.
Urea melt is sprayed through stainless steel nozzles onto seed particles inside the rotating drum. As the drum rotates, internal lifters tumble the material while cooling air solidifies the melt into uniform granules through controlled solidification and attrition.
Regular inspection of the abrasion-resistant lining and internal lifters is crucial due to continuous abrasive action. The spray system nozzles require periodic cleaning to prevent clogging, and support rollers/trunnions need lubrication and alignment checks to ensure smooth rotation.
