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.
