The rotary drum granulator is a core equipment in NPK fertilizer production lines, designed to uniformly mix and granulate nitrogen, phosphorus, and potassium raw materials with other additives. In the NPK manufacturing process, this rotating drum creates high-strength fertilizer granules through a combination of agglomeration, compaction, and polishing actions, while steam or liquid binders enhance particle formation. Its robust design ensures continuous operation, making it essential for producing homogeneous NPK blends with controlled nutrient ratios.

Versatile Granulation Equipment

The rotary drum granulator is a comprehensive granulation solution for large-scale production, capable of handling both cold and hot granulation processes for compound fertilizers with high, medium, and low concentrations. Its unique drum design offers optional special rubber lining or acid-resistant stainless steel lining that automatically removes wall buildup and lumps, eliminating the need for traditional scraper devices[1].

Outstanding Performance

This equipment is renowned for its high granulation rate and production of high-strength granules with uniform, attractive appearance. Featuring intuitive operation and significantly lower energy consumption than comparable systems, it also offers excellent corrosion resistance that substantially extends equipment lifespan[2].

Industry-Proven Solution

Through years of practical application, the rotary drum granulator has become one of the most mature granulation solutions in the compound fertilizer industry. Its innovative drying system ensures uniform moisture reduction, while modular design simplifies maintenance, dramatically reducing operational costs for manufacturers[3].

Broad Application Potential

From basic NPK compounds to specialized fertilizer formulations, the rotary drum granulator demonstrates remarkable adaptability. Its reliable performance and consistent output quality make it the preferred choice for modern fertilizer plants upgrading their production lines.
