Rotary Drum Granulator
Rotary drum granulator processes powdered or paste-like materials into uniform, granular particles. It's a key machine in fertilizer production, used for both organic and inorganic fertilizers.
Rotary drum granulators are suitable for large-scale production of high, medium, and low-concentration fertilizers. These fertilizer machines feature a special rubber or acid-resistant stainless steel lining that helps materials detach and fall away, preventing buildup.
This fertilizer granulation machine is mainly composed of a rotating drum, a transmission device, an inlet, an outlet, and internal granulation components.
