Rotary Drum Granulator: The Fertilizer Revolution?

In the compound fertilizer industry, rotary drum granulators are revolutionizing production with their unique working principle and outstanding performance. How does this seemingly simple rotating device transform raw materials into uniform fertilizer granules in just hours? Let's uncover its secrets.

The Art of Wet Granulation

The core appeal of drum granulators lies in their sophisticated wet granulation process. By precisely controlling water or steam addition, raw materials undergo physio-chemical reactions in the rotating drum. Particles collide and compress in moist conditions, eventually forming perfect spherical granules. This "soft approach" achieves over 95% granulation rate, with particle strength far exceeding traditional methods.

The "self-cleaning" design is a standout feature. Special rubber linings or acid-resistant stainless steel plates not only solve maintenance issues of traditional scraper devices but extend equipment lifespan by 3-5 years.

Multifunctional Reactor

The drum granulator is more than equipment - it's a versatile chemical reaction platform:

· Steam or gas injection to facilitate reactions

· Phosphoric acid or ammonia addition for NP compounds

· Handles both high and low concentration production

· Cold granulation with minimal moisture

This versatility makes it the heart of compound fertilizer lines.

Energy Efficiency Benchmark

Compared to traditional granulators, drum models show remarkable energy advantages. Optimized drum design reduces power consumption, intelligent temperature control prevents waste, while continuous operation boosts output. Statistics show over 30% energy savings, truly realizing "green production."

From simple granule formation to complex chemical reactions, rotary drum granulators are redefining compound fertilizer production. In today's pursuit of efficiency and sustainability, this may be the breakthrough the fertilizer industry has awaited.
