Industrial Natural Gas Rotary Kiln Dryer 500-10000kg/h 120-500℃

Rotary kiln dryer / Rotary drum dryer

Working principle:
  The rotary kiln dryer's drum is a slightly inclined, rotating cylinder. Wet material enters from the top of one end, and dry material is collected from the bottom of the other end. Hot air enters from either the feed or discharge end and exits from the top of the other end. The drum is equipped with forward-moving lifting plates, which continuously lift and scatter the material as the drum rotates, ensuring full contact with the hot airflow to improve drying efficiency and propel the material forward. After absorbing heat, the material rapidly evaporates its moisture. Fine powder in the humid air is collected by a cyclone separator and a bag filter before being discharged outdoors by an exhaust fan.

Features:

• Rotary drum drying has a high degree of mechanization and large production capacity.
• Low fluid resistance through the drum, resulting in low energy consumption.
• Strong adaptability to material properties.
• Stable operation, low operating costs, and good product drying uniformity.

Applications:

• Drying of large-particle, high-density materials in industries such as chemical, mining, and metallurgy, including: mine slag, blast furnace slag, coal, metal powder, phosphate fertilizer, and ammonium sulfate.
•  Drying of powdered and granular materials with special requirements, such as: HP foaming agent, distiller's grains, light calcium carbonate, activated clay, magnetic powder, graphite, and pharmaceutical residue.
• Materials requiring high-temperature drying and large-scale continuous drying.

Technical parameters:

Features:

•  Large heating area, high thermal efficiency, and uniform heating.
•  High operational flexibility and wide applicability. Various parameters such as feed concentration, film thickness, heating temperature, and rotation speed can be adjusted. Adaptable to drying various materials and different production volumes.
•  Short drying time, approximately 5-20 seconds, suitable for heat-sensitive materials.
•  Simple operation and convenient maintenance.
