MJW Consolidated has completed the installation of a new ball mill and associated equipment that will enable United States Gypsum’s Jacksonville, FL, plant to nearly double the capacity of one of its sheet rock lines.
A subsidiary of USG Corporation, United States Gypsum chose MJW to perform the work that included extensive pre-work to remove existing equipment and prepare the existing production area; unpacking and placement of new equipment; and assembly and connection of the new equipment. The major component of the upgrade was a 60,000-pound ball mill that contains 37,000 pounds of steel balls that pulverize raw gypsum to prepare it for the production line.
The scope of work included unloading the equipment components as they arrived on site, removing a wall from the building to stage the components, performing extensive hand rigging and construction of temporary supports to move the pieces into place, installation of cooling system piping, and completing the assembly and tie in of new bag unloading houses, twin screws and ball mill.
The work took place during a three-week outage on the line and required close coordination with the plant operations team prior to the start of the project. MJW crews self-performed all of the elements of the work to stay on schedule and finish the job safety.
