Particle Size Reduction Equipment

Every day millions of people use products we’ve had a hand in producing without realizing it. MPE manufactures industrial size reduction equipment critical for the production of many food, chemical, and mineral (FCM) goods and products.

Our state-of-the-art Gran-U-Lizer™ and Crack-U-Lator® equipment produce the most accurate particle size distributions that improve product yields and reduce unwanted fines. From cereal and peanuts to quartz and zinc, our grinding equipment can grind anything for commercial and industrial settings.

  • Gran-U-Lizers accurately cut and sheer product down to specific particle sizes—not crush
  • Crack-U-Lators produce narrow particle distributions with a controlled cracking process between longitudinal and/or circumferential cuts on mating rolls

Key Benefits

  • Reduce size to anywhere between 4 to 325 mesh or 4,760 to 50 microns
  • Less fines produced, meaning better yields and more profit
  • Complete CIP designs available
  • FDA food-grade and sanitary designs

Industry Leading Technology

MPE is the leading manufacturer of size reduction machines because of our countless innovations and features. Many aspects of our Gran-U-Lizers are chosen based on the intended grind application—including roll corrugations, speed ratios, hermetically sealed design, and others.
