The drum granulator is a specialized machine designed to form materials into specific shapes. As one of the key equipment in the compound fertilizer industry, it is suitable for large-scale production in both cold and hot granulation lines, as well as high and low concentration compound fertilizer production lines.

The primary working method involves aggregate wet granulation, where a specific amount of water or steam facilitates chemical reactions within the cylinder body. Under these liquid phase conditions, the rotating cylinder causes particles to collide and reunite, generating extrusion pressure that forms the material into spherical granules.

• High granulation rate of 70% with minimal returns; returned particles are small and can be re-granulated
• Steam heating capability to increase material temperature, resulting in lower water content in formed granules and improved drying efficiency
• Rubber engineering plastics lining prevents material sticking and provides corrosion resistance and insulation
• Large output capacity with low power consumption and minimal maintenance costs

• Innovative technology with improved structure; tube features special rubber sheet lining or acid-resistant stainless steel liner for automatic scar removal and deoma
• High wear resistance with convenient maintenance, excellent ball strength, superior appearance, corrosion resistance, low energy consumption, long service life, and easy operation
• Reasonable layout with advanced technology, minimal power requirements, no waste discharge, stable operation, and convenient maintenance
• High balling rate up to 70% with efficient drying; minimal returned material with small particle size suitable for re-granulation; steam heating capability to raise material temperature
