Grinding and Polishing Guide. Grinding should commence with the finest grit size that will establish an initially flat surface and remove the effects of sectioning within a few minutes. An abrasive grit size of 180-240 [P180-P280] is coarse enough to use on specimen surfaces sectioned by an abrasive wheel. Hack-sawed, bandsawed, or other rough ...

Mass measurement method for grinding media of sand mill. Mass measurement method = effective volume of sand mill x filling rate (75-85%) x media bulk density. In short, if the filling rate of the grinding media is too high, it is easy to cause an excessive temperature rise of the sand mill or blockage of the outlet.

Sand: This media is still used because of its low price but it can be costly in the long run. It is abrasive to the mill due to its irregular shape as it is more needle-like than spherical and the tips tend to break off. Waste disposal of this short term media can also be expensive. Alternative medias are glass and mullite.
