Grinding machines In materials processing a grinder is a machine for producing fine particle size reduction through attrition and compressive forces at the grain size level. See also crusher for mechanisms producing larger particles.
1. What's the Difference Between a Roller Mill vs. Hammer Mill? A hammer mill acts like the name implies by milling grain with a smashing motion. If you took a kernel of corn and smashed it, you would have multiple pieces with variation in size. A roller mill acts more like a cutting knife. As a roller spins, it creates a shearing effect.
