Who We Are

About Process Machinery, Inc. (PMI)

Founded in 1979 by David and Bill Miles, PMI began as a small operation in Louisville, KY, and has grown into a full-service provider for the aggregate industry. Now headquartered in Shelbyville, KY, PMI is recognized for delivering innovative, reliable solutions, trusted across the Eastern United States. Over the decades, PMI has evolved under the leadership of the Miles family, now guided by the third generation—Daniel Miles and Jennifer Ratterman—while continuing its legacy of innovation, quality, and collaboration.

At PMI, our people are our strength. From skilled engineers to field installation crews, every member of our team plays a critical role in delivering tailored solutions that exceed expectations. We’ve cultivated a culture where ideas are valued, and success is shared, driving both personal and organizational growth.
