Indirect Rotary Dryers

Built for performance and reliability, Vulcan® Indirect Rotary Dryers produce quality and replicable drying results. Our Indirect Rotary Dryers are one of the most versatile industrial dryers on the market. Our modular approach allows you to pick the dryer size, flight arrangement, burner and air pollution control equipment to best suit your unique project. Vulcan® Indirect Rotary Dryers are built to rigorous safety and performance standards because they are 100% designed, manufactured and tested in the USA.

Vulcan® Indirect Rotary Dryers rely on the heat transferred through the drum’s shell to dry the material via conduction and radiation to reduce the material’s moisture content. Indirect drying allows you to tightly control the processing environment, an ideal characteristic when working with materials that can be combustible or where higher temperatures are required to remove bound water. Our indirect dryer units can have tumbling flights (optional) and an air stream heat exchanger (optional) mounted in the combustion chamber stacks to utilize waste heat to heat sweep air and increase drying efficiency.

Vulcan®'s Indirect Rotary Dryers come in standard sizes ranging from 3’ diameter by 15’ long to 8’diameter by 60’ long. Whether you have a small 1TPH project or a large 200TPH project, we can construct your dryer to fit your project.

Standard Dimensions:

     Diameter: 36"-96"

     Length: 15' - 40'

Long Dimensions:

     Diameter: 36"-96"

     Length: 22' - 60'

Vulcan®'s Indirect Rotary Dryers are constructed from a variety of materials depending on your application. Each standard dryer has four options for you to choose from, but we can construct your dryer from any material that you

  • 1/4" 304 Stainless Steel for Light Industrial, Low Temperature Applications
  • 3/8" 304 Stainless Steel for Heavy Industrial, Low Temperature Applications
  • 3/8" Inconel for High Temperature Applications
  • 1/4" 316 Food Grade Stainless Steel

Your indirect rotary dryer can be customized with a number of flight options from standard to aggressive (or a combination). Knock out boxes can be added for your controls, insulation and wraps to better control temperature and an external finish paint to keep your dryer looking new for years.

  • Flights
    • Standard
    • Aggressive
    • Combination
  • Over sized Knock Out Box
  • VFD Drum Drive
  • Insulated shell with aluminium skin
  • Internal Hard Refractory (Not for drying applications)
