Patent number: 10835903Abstract: The system and method requiring a diverter plate for an in-line mill. The plate for use with the in-line mill includes an aperture for passage of particulate laden fluid therethrough and a plurality of tabs such that the fluid and the particulate entrained thereon is deflected at a variety of axial angles. The diverter plate thus provides a reliable method such that the milling process and component wear resistance is made more efficient thereby.Type: GrantFiled: September 19, 2016Date of Patent: November 17, 2020Assignee: UCC Dry Sorbent Injection, LLCInventors: Dennis Engelmann, Stephen Bosshart, Eric Fleckten, Harun Bilirgen, Robert LeDain

Publication number: 20170173516Abstract: 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.Type: ApplicationFiled: January 9, 2017Publication date: June 22, 2017Inventors: Jon Balbarin, Daniel E. Charhut, Robert Heywood, Robert LeDain, Saurabh Rastogi
