Rotary drum fertilizer granulator is one of the critical machines in compound fertilizer production line. It is applied to cold, hot granulation and quantity production of high, medium or low concentration compound blending fertilizer.

The granulating method involves rolling round fertilizer particles in wet granulation. With water or vapor added, the original fertilizer in the rotary drum is blended uniformly and becomes humid. During this process, the fertilizer reacts and, through the liquid environment and rotation in the drum, the fertilizer particles squeeze each other and roll into fertilizer particles measuring 3-4mm.

• High fertilizer particles rolling rate of approximately 70%, with minimal returning fertilizer that can be regranulated
• Vapor or water addition improves fertilizer temperature and creates high-quality fertilizer particles
• Engineering plastics used for inner lining prevent sticking, provide anti-corrosion and thermal insulation
• Large granulating capacity with low energy consumption and maintenance costs
• Flexible fertilizer particle diameter according to different formulations, processing procedures, and raw materials
• Superior quality steel materials with strict quality requirements and control
• Low noise, stable performance, and rational structure including shoveling plates for drum cleaning

• Granulator bracket: Supports the entire rotating part using medium carbon steel plates and channel beam materials welded to strict quality standards
• Drive part: Gear frame welded from high-quality channel beam with ISO National Free-inspection Product motor and reduction gears
• Large gears: Fixed on granulator and meshes with small transmission gears using high-tech wear-resisting materials for extended service life
• Rolling belt: Fastened on both sides of granulator for support

• Sludge drum granulation process
• Sludge organic and inorganic fertilizers drum granulation process
• Livestock manure organic drum granulation process
• Industrial waste organic fertilizer drum granulation process
• Compound fertilizer steam drum granulating process
