A section of the rotary kiln system at the Graymont lime plant in Green Bay, Wisconsin, captured at night under maintenance and work lights. The massive rotating kiln—central to the calcination process that transforms limestone into high-purity lime—runs along a network of elevated platforms, access stairs, and steel supports. The orange glow from overhead lamps highlights the heat-intensive nature of kiln operations, while the surrounding catwalks and conveyors reflect the layered engineering required to keep the continuous production line moving.

Illuminated by a single amber work light, the upper platforms and transfer pipes of the Graymont lime plant in Green Bay, Wisconsin stand out against the night sky. The cylindrical storage silos are connected by enclosed conveyor and piping systems that move processed lime between different stages of production. Catwalks, ladders, and pipe supports trace the geometry of an industrial site that has long supplied lime for regional steelmaking, water treatment, and construction uses.

A detailed nighttime view of the conveyor towers and processing equipment at the Graymont lime plant in Green Bay, Wisconsin. The illuminated catwalks, ducts, and steel trusses highlight the facility’s continuous material-handling system, where crushed limestone moves through enclosed conveyors toward the plant’s kilns and storage silos. Fine dust, visible in the lights near the upper platforms, reflects the industrial character of a site that has served the region’s construction and manufacturing sectors for decades.

The Graymont lime processing plant along the Fox River in Green Bay, Wisconsin, illuminated during nighttime operations. The facility’s network of silos, conveyors, and dust-collection towers stands out against the dark sky, with steam drifting from active kilns and processing units. Reflections from the plant’s industrial lighting shimmer across the frozen river surface, highlighting the site’s role in the region’s long-standing manufacturing and mineral production corridor.
