Abstract: A method for descaling a sheet of metal include first and second descaling components that each have a single motor driven slurry propelling impeller mounted on a top and bottom of an enclosure. The top and bottom mounted impellers of the first component are configured to propel slurry onto a sheet of metal passing through the enclosure across the entire width of the sheet of metal in a first direction extending from one lateral side to an opposite lateral side of the enclosure. The top and bottom mounted impellers of the second component are configured to propel slurry onto a sheet of metal passing through the enclosure across the entire width of the sheet of metal in a second direction opposite the first direction and extending from the opposite lateral side to the one lateral side of the enclosure.
