Drum granulator is a machine that transforms materials into specific shapes and serves as one of the key equipment in the compound fertilizer industry. It is suitable for large-scale production in cold and hot granulation lines, as well as high and low concentration compound fertilizer lines. The primary working method involves aggregate wet granulation, where a specific amount of water or steam enables chemical reactions within the cylinder body. Under these liquid conditions, the rotating cylinder facilitates particle aggregation and extrusion pressure to form spherical granules.

• Granulation rate of 70% with minimal returns; returned particles are small and can be re-granulated
• Steam heating capability increases material temperature and reduces moisture content in formed granules, improving drying efficiency
• Rubber engineering plastics lining prevents material sticking and provides corrosion resistance and insulation
• High output capacity with low power consumption and minimal maintenance costs

The potassium sulphate compound fertilizer granulator is a highly versatile piece of equipment capable of processing a wide array of materials. Designed for high-capacity applications, it typically requires some type of recycle system depending on product specifications. Drum Granulators are specifically used when an Agglomeration - Chemical Reaction Process is required.

As a key equipment in the fertilizer industry, the drum granulator is applicable to cold, heat, guniting, and ammoniated granulation processes, supporting large-scale fertilizer production across high, medium, and low concentration requirements.

The cylinder body can be constructed with special stainless steel or rubber plate lining structure. It features automatic scar removal and peeling burl elimination. Key advantages include high granule intensity, superior production capacity, corrosion and abrasion resistance, low energy consumption, extended service life, and convenient operation and maintenance.
