Decades of know-how behind every DustMASTER machine.


DustMASTER® Enviro Systems is dedicated to the mixing and management of industrial materials and byproducts worldwide. As a division of Mixer Systems, Inc., DustMASTER utilizes their expertise in the design and manufacture of material handling equipment, batch plants and mixers for environmental and industrial markets.

Mixer Systems was formed when company founder William Boles purchased the Turbin & Tilter mixer lines in 1979 from the T.L. Smith Company, based out of Milwaukee, Wisconsin. T.L. Smith introduced the pan mixer (now known as the legendary Turbin Mixer) concept to North America in 1955. With more than 3,000 Turbin Mixers sold, Mixer Systems is the largest producer of pan mixers in North America.

Mixer Systems established DustMASTER in 1984 to introduce its mixing technology and expertise to industrial markets that have dust management needs.

Responding to the opportunities of emerging markets, DustMASTER is also deploying our solutions to mix and manage materials beyond industrial dusts. From aerating to homogenizing to slurrying and more, the capabilities of DustMASTER equipment are virtually unlimited.


To ensure quality and durability, DustMASTER manufactures each mixer—including its customized controls-at our 86,000 square-foot headquarters.
