Material Science

If the sample is extremely heat-sensitive or has a high fat content, embrittlement generally enhances the grinding process as the cooling counteracts the frictional heat effects. When dry ice is used as grinding aid, this has to be mixed with the sample in a 2:1 ratio and then the ZM 200 pulverizes the complete mixture.Get price
