After a couple of years, rotating kilns tend to lose their roundness. The traditionally used seals (carbon rings) wear out on the largest diameter, which in the end causes air ingress because of negative pressure. As a result, the firing process is being disturbed, COx- and NOx-emissions increase and the use of energy rises, with all the costly consequences. To prevent these problems, our engineers developed Wearflex® Dynamic Seals.
Wearflex® Dynamic Seals are flexible seals, which are installed on the stationary part of the kiln. The sealing takes place where the wear resistant part of the seal is being strapped down on the rotating part. Wearflex® Dynamic Seals follow the shape of the rotary kiln and reduce the ingress of cold air into your kiln by ensuring a perfect seal between the rotating and static parts of your application.
Wearflex® Dynamic seals reduce heat loss and COx and NOx emissions. You will save energy!
Many variations of flexible sealing are possible, depending on the specific design of the kiln. At our state-of-the-art production facility, our skilled employees manufacture various custom-made, high-quality Wearflex® Dynamic Seals.
