  • Publication number: 20170173516
    Abstract: The system and method for preventing air leakage from the process side to the bearing side of a mill. The system includes a labyrinth seal ring comprising a series of knives defining first and second labyrinth paths from an air inlet to the process side and the bearing side of the system, respectively. The differences in the two paths such as provided by the number of knives used in each path creates a differential pressure drop which biases air from the air inlet to the process side. The labyrinth seal thus provides a reliable and superior method for reducing the potential for particulate in the process side of the mill from damaging the bearing system.
