Chinese power-station coal mills use Espey shaft-seals to

This brief case study looks at a sealing system that is being used in coal mills at a power station in Dezhou, China. The mills produce 'coal dust' which is used to fuel steam generators. Designed and developed by German company Gustav Espey , the seals have proved to be highly reliable and robust, preventing any 'coal dust' from being discharged into the atmosphere.
