Smoky Valley Roller Mill, Historic roller mill and museum in Lindsborg, Kansas.

The Smoky Valley Roller Mill is a three-story brick building constructed in 1898 that houses original Wolf Company roller milling equipment and machinery. The equipment was originally powered by water turbines from the nearby Smoky Hill River, demonstrating late-1800s industrial technology.

Smoky Valley Roller Mills was built in 1898 to grind wheat into flour and passed through several owners. It closed temporarily from 1927 to 1934 and shut for good as a working mill in 1955; water power gave way to electricity in the 1930s. McPherson County received the building in 1962, and Malcolm Esping of Lindsborg and George Tesarek, a retired Quaker Oats miller from St. Joseph, Missouri, led its restoration from 1974 to 1981. It joined the National Register of Historic Places in 1972.

The museum grounds hold the 1904 World's Fair Swedish Pavilion, moved to Lindsborg, alongside buildings with exhibits on Swedish-American history. The site is run by a nonprofit formed in 2021, and the mill's machines are shown working during Millfest each May.

The museum is open Monday through Saturday year-round, closing only on specific holidays. It occupies Mill Street in Lindsborg, and the grounds hold several buildings, including the 1904 World's Fair Swedish Pavilion, so allow time to walk between them. During Millfest in May, the mill's machines run from line shafts driven by a large electric motor outside the building.

The building preserves perfectly maintained Wolf Company roller milling equipment from Pennsylvania that still operates using line shafts during public demonstrations and special occasions. This drive system shows how industrial mills distributed power during that era.
