Abstract
Jacks are positioned about the base of a coal pulverizing bowl mill to elevate the separator housing which contains and supports the journal rolls. The separator housing is raised by the rollers attached to the jacks. Once raised, the housing is rotated to sequentially position the access door of each journal roll to the front of the mill. A mobile crane conveyance is stationed at the front of the mill to remove and replace each journal roll through its access door.
