High Granulation Rate Rotary Drum Granulator for NPK Fertilizer Production with Low Moisture Content and Adjustable Granule Size

The rotary drum granulator developed by our company is carefully engineered and rigorously tested. This advanced equipment produces spherical granules at room temperature with optimal structural design. The resulting granules feature low water content, easy drying, high formation rate, excellent granule strength, and attractive appearance. It serves as an ideal granulation solution for bio-organic fertilizer, organic-inorganic fertilizer, and organic-inorganic compound fertilizer production.

The new drum granulator efficiently processes various organic wastes including peat, sludge, chicken manure, livestock and poultry manure, lignite, sugar factory filter mud, papermaking sludge, brewing residue, straw, bean dregs, and peat. These materials can be directly granulated after fermentation, effectively solving the key technical challenge where traditional granulation processes like disc fermentation cannot granulate biological organic fertilizer raw materials.

The cylindrical centrifugal granulator employs a unique process using a winch mechanism to stir and feed materials. Through spiral rotating mechanisms and centrifugal force, powdered materials undergo comprehensive processing including balling, polishing, compaction, and drying to achieve bonded spherical particles. The resulting particle size typically ranges between 0.3-0.5mm with approximately 30% moisture content and achieves over 95% granulation rate. This system effectively granulates various fermented organic materials including chicken manure, pig manure, cow manure, humic acid, and other organic powdered substances.

• Advanced granulation process integrating rotation, spheroidization, polishing, densification, heating, and drying functions
• Spiral rotating mechanism constructed from high-strength alloy materials for exceptional durability and extended equipment lifespan (virtually no wearing parts)
• Granulation capability with material moisture content between 30-40%, significantly reducing the traditional 70% moisture requirement and lowering organic fertilizer production costs
• Cylinder generates 50-65°C temperatures during granulation, reducing output material moisture by 5-8 points and decreasing drying cost requirements
• Produces uniform, smooth, round, and solid particles with over 95% formation rate
• Adjustable discharge particle size by modifying feed material moisture content to meet various particle size specifications
• Feed fineness control at approximately 20 mesh for granulation, improving upon traditional process requirements of at least 80 mesh
