Roller Mill Installation

Keeping the Momentum

The United States Gypsum Company contracted REDD to provide detailed engineering design and project management services to install a new 74” Williams Roller Mill and associated chutes on the top floor of a new 100 foot tall structure.

Gypsum board or gyp board is known throughout the country as sheetrock because of USG’s clever use of the term.

Roller Mill Installation

The Texas Sweetwater Plant determined that the existing mills had become a significant bottleneck. To meet current and forecasted needs, United States Gypsum (USG) hired REDD to provide engineering, procurement support and construction management services to install a 74” fluid bed roller mill system capable of milling a nominal fifty tons per hour of 2” minus gypsum rock.

The plant was in full production throughout the project, we were allowed a small window to make final tie ins.

Additionally, the mill needed to suspend 100 feet above grade to tie into the existing chute system. The equipment weighed nearly 10 tons.

This installation provided the Sweetwater Plant with a continuous supply of landplaster to meet current production demands and allow required maintenance to be performed on the other mill lines.
