The origin of CPM can be traced back to California's Napa Valley, where in 1883, the Toulouse & Delorieux Co. manufactured presses, crushers and stemmers for winemakers. In 1931, the company created the first pellet mill, the 30 HP "Flat Bed" with stationary flat die, and we became California Pellet Mill (CPM).

In the years that followed we created more pellet mill models with additional features. In 1980, we greatly expanded our product offerings through the creation of Roskamp Champion with the purchase of the Roskamp Roller Mill Company and Champion Hammermills.

In 2002, we purchased Beta Raven, a leading supplier of feed mill automation and ingredient scaling systems. Since then, we have added Crown Iron Works, a global leader in thermal, mechanical and chemical process equipment; Century Extrusion, an industry leader in extrusion equipment and parts; Wolverine Proctor, world leader in thermal processing applications; Nanjing Ruiya Polymer Processing Equipment, a leading provider of complete compounding systems, including twin screw extruders; and Greenbank Technology Ltd., manufacturer of high-value thermal process systems including dryers, ovens, washers, air pollution control and heat recovery systems. Most recently, we acquired the assets of Lauhoff Corporation of Detroit, Mich., including all intellectual properties for rotary pressure cookers, flakers, stem crushers and ancillary equipment. These assets have been combined with our Wolverine Proctor division.

With facilities around the world, we sell and service machinery and equipment in Europe, Asia, Latin America, North America and other parts of the world. We are the world’s leading supplier of process equipment to the animal feed and the oilseed processing industries. We also serve the corn wet milling, pet food, ethanol, wood and microbrewery industries, and we are the world leader in particle size reduction equipment.
