This week’s photo shows the interior of a rotary kiln, as a technician works to remove build-up on the refractory.
Build-up can sometimes occur in an over-temperature condition which causes product to melt and become sticky. A primary design requirement with all rotary kilns is that the material needs to be free-flowing and tumbling as it moves down the length of the drum. This can result in dams inside the kiln, which further disrupt the operation, potentially resulting in a backspill at the feed end.
