In continuous compound fertilizer production lines, NPK compound fertilizer production lines, and environmental sludge processing, converting liquid slurries or pastes into uniform dry granules is a critical process. A spray granulator (also known as a spray drying granulator) is an industrial apparatus that integrates atomization, drying, solidification, and pelletizing into a single continuous step to produce spherical granules with controlled particle size distribution and high strength.

As a professional compound fertilizer equipment manufacturer and fertilizer equipment manufacturer, Taian Hongxin Environmental Protection Equipment Co., Ltd. delivers high-performance fertilizer granulating equipment as part of our complete fertilizer processing machinery solutions globally.

I. Structural Components & Technical Features

A complete spray granulator system consists of a rotary drum body, drive unit, feeding system, discharge mechanism, atomization nozzles, heating system, transmission setup, and electronic control system.

• Large Specifications & High Capacity: Typical drum diameters range from Φ3.5m to Φ4.5m, delivering a continuous production output of 2 to 12 tons per hour.

• One-Step High Efficiency: Direct conversion from liquid feed to dry granules drastically reduces process complexity, lowering operational costs.

• Superior Granule Quality: Produces highly uniform, spherical granules with good flowability, high mechanical strength, and minimal dust formation.

• Durable & Stainless Steel Options: Available in heavy-duty carbon steel or premium stainless steel (e.g., SS304 / SS316L) to handle corrosive agricultural slurries or chemicals.

II. Primary Industrial Applications

1. Fertilizer Industry:

   • Application: Functions as key fertilizer production equipment in NPK compound fertilizer production lines and ammonium phosphate processing.

   • Advantages: Enhances nutrient distribution uniformity, granule fluidity, and anti-caking properties for easy field application.

2. Environmental Protection:

   • Application: Widely used for drying and granulating industrial and municipal sludge slurries.

   • Advantages: Achieves waste volume reduction, stabilization, and harmless treatment, facilitating easy transport and land application.

3. Chemical & Material Processing:

   • Applied in food additives, detergents, catalysts, and dyes to convert pastes or liquids into free-flowing spherical powders.
