In 2019, Mixer Systems marked our 40th anniversary of American-made mixers and material handling equipment. William Boles established Mixer Systems when he bought the T.L. Smith Company of Milwaukee and took over manufacturing of the legendary Turbin pan-style mixer. In the ensuing years, Mixer Systems has expanded our product line, all made at our headquarters facility in Pewaukee, Wisconsin. The DustMASTER Enviro Systems Division formed in 1984, adopting the mixing technology of Mixer Systems and extending it to new markets. Mixer Systems commemorated our anniversary by publishing a series of trade advertisements highlighting company products and services.
