Resolving Refractory Failure in Rotary Kiln kiln
The rotary kiln refractory not only protects the shell interiors when the kiln is in use, but also minimizes heat loss, thereby reducing resource consumption and operational costs. However, if the refractory fitted in your kiln is damaged or subpar, it can have a direct impact on your process efficiencies, as well as the longevity of the kiln.

Professional Kiln Manufacturer
Rotary kilns are designed to withstand much higher temperatures than a rotary dryer. Typically, if you are dealing with a direct fired rotary kiln, it is refractory lined with a brick or castable lining. This lining protects the steel shell. Rotary dryers are typically not lined, and their steel is not able to withstand such high temperatures.

How Does A Rotary Kiln Work?
Rotary kilns can be either directfired, or indirectfired (calciners). Directfired kilns use direct contact between the material and the process gas to cause the reaction, whereas indirect kilns rely on the heat emanating from the shell of the drum, which is externally heated to temperature.
