Rotary Dryer

The rotary dryer are sued to remove excess moisture from fertilizer materials quickly and efficiently to prepare them for cooling, screening, packaging, or further processing. It can operate as a standalone drying system or be integrated into a complete fertilizer production line. Our rotary dryer provides reliable moisture control for consistent product quality and efficient fertilizer processing.

As the drum rotates, the material gradually moves through the dryer. Heated air flows around the material to transfer heat and remove moisture efficiently. Our patented combination lifting flights are configured according to different fertilizer materials and drying zones, increasing material dispersion and improving heat transfer throughout the drying process. This design delivers faster drying with lower energy consumption. A high-capacity induced draft system increases contact between the material and hot air to remove moisture efficiently while supporting compliant exhaust emissions. Patented energy-saving technology further improves thermal efficiency through optimized hot air utilization and waste heat recovery. The combination lifting flights inside the drum also enhance heat exchange, reducing overall energy consumption by 15–20%.

Features
  • Easy Installation and Transportation

    The flanged drum structure simplifies equipment assembly, transportation, installation, and routine maintenance.

  • Real-Time Temperature Monitoring

    Thermocouples are installed at both the feed and discharge ends of the dryer, allowing operators to monitor temperature changes throughout the drying process and maintain an operating temperature of 350–380°C.
