Founded in 1844, Rotex Group had the pleasure this year of celebrating its 180th business anniversary. From our founding as the Isaac Straub Mill Company, to the invention of the Rotex Screener, all the way through to today with our full lineup of industrial sifters and separation equipment, we’re proud of our history and what it means to our company, our associates, and the future of our industry.

The celebration was marked by an open house event held at the Rotex Group headquarters in Cincinnati, where employees and their families were invited to witness firsthand our machinery in operation and the processes that have made us a global leader in the industrial separation industry. The event was not just a celebration of the company’s longevity, but also a showcase of the technological advancements that continue to be a cornerstone of its success. Most importantly, the event was held in recognition of all our associates, business partners, and customers, both past and present, for playing such a pivotal role in our company’s rich history.

The event featured presentations from Rotex Group President Lawrence Rentz, Hillenbrand CEO Kim Ryan, and Cincinnati Mayor Aftab Pureval. Their speeches highlighted the company’s journey, its achievements, its vision for the future, and its connection to an enduring legacy of technological innovation and advancement in the city we call home. The event was also marked by commemorations from the Ohio Governor’s Office and the Ohio State Senate.

As we step into our 181st year, we do so with a renewed commitment to excellence and a vision to continue shaping the future of the industrial screening industry. Our journey is a testament to the power of innovation, the importance of resilience, and the value of a committed workforce. Here’s to the next 180 years…
