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.
