New Owners Take the Controls at Mixer Systems, Inc.

New Owners Take the Controls at Mixer Systems, Inc. for the First Time in a Generation.

Pewaukee, Wis., July 25, 2023 — Mixer Systems, Inc., North America’s premier manufacturer of mixing and batching equipment for the concrete, glass, and environmental industries, today announced new ownership and promotions of the management team.

Family owners Lesley Hill and David Boles, who shared leadership of the company, sold a majority stake to a group comprised of a Milwaukee-based growth partner and Mixer executives. This is the first change of ownership outside the family since Mixer was founded by William Boles, father of Hill and David Boles, in 1979. The siblings retain minority ownership in the company.

As part of the ownership transition, Doug Duley, president of Mixer, has been promoted to CEO, and Nicholas Passint, general manager, has become president. In addition, Scott Adams, general manager of the DustMaster division, will be expanding his role with Mixer and taking on the GlassMaster product line.

“We’re extremely grateful to Lesley and David for their steady leadership in guiding Mixer forward after the death of William Boles in 2014,” said Duley. “While we’ll miss their energy and spirit, we congratulate them on their retirement and wish them well in spending more time with family and pursuing their passions outside of Mixer.”

The ownership and management changes are expected to bring new capital to Mixer and help position the company for significant growth in the years to come, while also maintain its innovative tradition. Mixer presently makes the largest line-up of mixers and related equipment in its industry.

“This is a truly exciting time for the company as we look to a new chapter of being an industry leader and continuing to provide the best possible solutions for our customers,” said Passint. “Our products will still proudly wear the ‘Made in America’ label to reflect the engineering, craftsmanship, and reliability for which Mixer is known worldwide.”

Enterprise Precast, Corsicana Texas

A diversified economy and population growth are tempering the effect depressed energy prices would traditionally have had on the Texas construction market, where commercial building work held strong this year on the heels of surging 2013–14 activity. One of the most recent arrivals in architectural precast production, Enterprise Precast Concrete of Texas, LLC, is set to close out a year when historic rainfall totals—40 inches or more in some central and eastern parts of the state, or four times their normal annual precipitation levels—were as disruptive as oil dropping to $40/barrel.

Mixer Systems Part of New Solution

A contractor upgrading a Whiting, Ind., petroleum refinery recently tapped a distant precast producer for a mostly rectangular vault , one side with a slight, coffin-like angle to accommodate site infrastructure. While customized recast concrete might economically “travel” farther than a standard product, it takes unusual circumstances to justify
shipping a mundane, 75-ton under ground structure from near the Gulf of Mexico to the southern tip of Lake Michigan.Mixer-Systems-Planetary-Mixer

Houston-based Locke Solutions recognized site, labor and safety circumstances surrounding the refinery structure, and delivered a precast solution for a customer mindful of cast-in-place methods’ quality control and schedule variables. The upstart producer thrives on oddball requirements and one-of-a-kind jobsite conditions calling for product fabricated beyond ASTM or related parameters.

Locke Solutions capped its second year in production with a batch plant installation. Mixer Systems furnished a 1.5-yd. planetary mixer, whose twin discharge doors feed buckets transferred by tandem overhead cranes. The batch plant has a 2- to 2.5-minute cycle time, depending on mix design, and affords plant crews the option of
a single 1.5-yd. load or a double batch in a 3-yd. bucket. Mixer Systems also equipped the operation with two 30-ton sand & gravel bins, plus 350-bbl cement silo. The plant runs on E-150 touch screen controls, for which up to 50 mix designs can be programmed.
