  • Difference Between Roller Compaction And Milling

    A roller compactor generally consists of three major units: a feeding system, which conveys the powder to the compaction area between the rolls; a compaction unit, where powder is compacted between two counter rotating rolls to a ribbon by applying a force; and a size reduction unit, for milling the ribbons to the desired particle size.Difference between roller compaction and milling,Nov 28, 2016The difference between a roller mill and a hammer mill is: A hammer mill uses rotating hammers to pound grain through a screen and it requires a lot of horsepower You get a lot of powder with larger deviation from the hammering difference between roller paction and milling
