Hammer mills versus rolles mills - La Meccanica

2021-7-11  The most common grinders are the hammer mills and the roller mills. They have been applied to the task of particle size reduction or grinding in feed milling applications. Roller mills have been used in the processing of common feed materials for years. The earliest roller mills used in the feed milling were abandoned flour milling roll stands, used primarily to produce coarse granulations of

What's the difference between a Roller Mill and a

You get a lot of powder with larger deviation from the hammering. A roller mill uses cylindrical rollers that grind the grain when it goes through them, which requires less horsepower then a similar capacity hammer mill. A roller mill gets a more consistent grind and smaller deviation then a hammer mill by rolling the grain instead of hammering it.
