Rotary Drum Granulator for Organic Fertilizer with 95% Granulation Ratio, 1-10mm Pellet Size, and Carbon Steel Build

Heavy duty bio-organic fertilizer granulating equipment designed for premium production requirements.

This machine merges a high-speed stirring pin system with a traditional rotary drum:

• Raw materials enter the front stirring section first
• High-speed mechanical force creates dense micro-agglomerated "seed granules"
• Seeds move into the rear drum section
• Drum rotation uses gravity and centrifugal forces to roll seeds repeatedly
• Coating process applies remaining powder and polishes surfaces
• Produces highly uniform, dense spherical granules

Engineered for large-scale bio-organic fertilizer production lines with annual output exceeding 30,000 tons. Ideal for premium producers requiring strict granule spherical uniformity and smooth, retail-ready product appearance.

Compatible with various organic formulations including:

• Fermented livestock manure blends
• Straw powder and biochar
• Amino acid powder and molasses
• Microbial inoculants
• High-viscosity or fiber-rich organic formulations
• Materials with organic matter content exceeding 50%
