Unlike conventional dryers that are manufactured in sections and assembled on-site, this project required the dryer to be delivered as a complete, factory-welded single piece. The purpose of this design is to eliminate the need for on-site welding, ensuring higher installation precision, faster commissioning, and improved mechanical alignment of the rotary body. This approach has gained increasing popularity among overseas fertilizer plants seeking faster project completion and more reliable long-term operation.

The 30-meter one-piece dryer was designed for high-temperature drying of DAP (Diammonium Phosphate), NPK compound fertilizer, and ammonium nitrate granules. The internal structure includes a scientifically arranged lifting plate system, adjustable feeding device, and multi-stage sealing design to ensure high drying efficiency and minimal heat loss. The dryer operates under a fully controlled temperature profile, capable of maintaining a uniform outlet moisture content between 1.5% and 2.5%, ideal for subsequent cooling and screening operations.

Our engineering team adopted advanced finite element analysis (FEA) during the design stage to ensure mechanical strength and thermal stability of the long rotary shell. The main cylinder is fabricated from Q345R pressure vessel steel, fully welded in our workshop under TUV and CE standards, and every seam undergoes ultrasonic and radiographic NDT inspection. After welding, the shell was subjected to stress-relief heat treatment to prevent deformation during high-temperature operation.

However, the benefit of no on-site welding also brings a key logistical challenge — transportation cost.

The dryer will play a vital role in the pipe reactor DAP and ammonium nitrate production process, where slurry generated from the pipe reactor requires precise moisture control for granulation and coating. The high-efficiency design ensures energy savings, low emission levels, and stable product quality, meeting both environmental and performance standards of the modern fertilizer industry.

This shipment once again proves our company’s capability to design, manufacture, and deliver large-scale rotary equipment for international fertilizer projects. With decades of experience in rotary drum dryers, granulators, and kilns, and full compliance with CE, TUV, and ISO9001:2015 quality standards, we have established long-term partnerships with clients in Egypt, India, Vietnam, and Latin America.

As fertilizer production technologies like pipe reactor granulation and ammoniation systems continue to evolve, the demand for energy-efficient, pre-assembled rotary dryers will continue to rise. Our factory remains committed to offering customized engineering solutions that combine high precision manufacturing, global shipping expertise, and reliable after-sales support.

The successful delivery of this 30m one-piece dryer to Egypt highlights not only our technical strength but also our dedication to helping customers achieve efficient, sustainable fertilizer production with reduced installation time and improved plant performance.
