Carbon Steel Rotary Drum Granulator Machine with 70% Granulating Ratio and Corrosion Resistant for Fertilizer Production

Rotary Drum Granulator machine is a critical component in fertilizer production processes. Its quality directly determines the efficiency and quality of the end product. Pellets produced via this granulator machine are denser and more spherical than those created through other agglomeration methods.

As one of the key equipment pieces in the fertilizer industry, the rotary drum granulator is applicable to both cold and heat granulation processes, supporting large-scale fertilizer production with high, medium, and low consistency materials.

We offer various configurations to suit your specific fertilizer processing needs, whether for organic or inorganic applications.

• Granulating ratio of up to 70%, with minimal feed material requiring re-granulation
• Cylinder body features rubber plate lining structure to prevent raw material agglomeration
• Automatic scar removal and burl peeling capabilities
• High intensity granules with superior quality, corrosion resistance, and abrasion proofing
• Low energy consumption with long service lifespan
• Easy maintenance and operation

The rotary drum granulator machine is designed for producing both organic fertilizer granules and NPK compound fertilizer granules. It can be integrated into organic fertilizer production lines or NPK fertilizer production lines to create high-quality fertilizer granules.

This machine typically employs wet granulation methods to complete the granulating process efficiently.

The machine utilizes high-speed rotating mechanical shearing force and resulting air power to continuously implement mixing, granulating, spheroidizing, and density processes for fine powder materials.

Key performance characteristics include:

• Spherical particle shape with sphericity of 0.7 or higher
• Particle size typically between 0.3 and 3 mm
• Granulating rate of 90% or higher
• Adjustable particle diameter based on mixture quantity and spindle speed
• Lower mixing volume and higher rotational speed produce smaller particles
