About Us


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 the 1980s, we greatly expanded our product offerings through the creation of Roskamp Champion with the acquisition of the Roskamp Roller Mill Company and Champion Hammermills.

In 2002, Beta Raven, a leading supplier of feed mill automation and ingredient scaling systems, joined the team.

Since then, we have added:

  • Crown Iron Works, a global leader in thermal, mechanical and chemical process equipment
  • SKET, a leading provider of engineered solutions and process equipment in preparation, refining and oleochemical processing
