Deha Tech has been a leading for the rotary kiln and rotary dryer industries for many years. From models as small as 2-foot diameters to massive tubes with 60-ton wall sections,

Rotary Kilns are large rotating steel tubes that cause chemical reactions by heating up solids as the material passes through them.

Typically, they can withstand much higher temperature ranges than rotary dryers, operating between 1,000 degrees Fahrenheit and 3,000 degrees Fahrenheit.

Rotary kilns come in two different types:

  • Direct fired rotary kilns: Consist of a steel shell lined with a protective brick or castable lining to withstand extreme temperatures.
  • Indirect rotary kilns: Unlined kilns with shells made from a temperature-resistant alloy rather than steel.

Rotary dryers, on the other hand, dry products by drawing moisture out of them, as their name suggests. However, rotary dryers can only handle temperatures ranging from 800 degrees Fahrenheit to 1,400 degrees Fahrenheit because, like indirect kilns, they lack a protective refractory liner.

Rotary dryers also come in two variations:

  • Direct rotary dryers
  • Indirect rotary dryers
