“Our seals consist of a proprietary carbon-fiber-based material with a special coating for better sealing and low friction values,” explains Application Engineer Markus Ittner. The seal housing for a rotary kiln rests on a rotating disc, just as a brake caliper does on a car’s brake disc. Pre-loaded springs hold the seals against the disc, providing the requisite contact pressure. EagleBurgmann’s sealing material is also self-lubricating, which minimizes friction losses and reduces the amount of primary energy needed to run the system. This aspect, too, makes the seals particularly sustainable.
The comprehensive package that EagleBurgmann offers for kiln manufacturers and plant operators also includes an expansion joint, which compensates for the expansion of the kiln shell produced by the tremendously hot process gases. Given the growing emphasis on environmental safety and energy efficiency, EagleBurgmann’s sealing system is becoming a more and more appealing choice for plant operators.
