Mill scale (also called scale) is the flaky surface that forms on hotrolled steel. Its composition includes FeO (iron (II) oxide), Fe2O3 (iron (III) oxide), and Fe3O4 (iron (II,III) oxide). You will find mill scaling on steel sheets, plates, and profiles. It arises when you roll hot steel billets or iron in rolling mills.

If the mill is rotated too fast, the balls can be thrown too far and just strike the far end of the mill and conversely, if the mill is rotated to slow, the efficiency of the grinding process significantly reduced. Ball mills are suited for finer grinding as larger particles do not impede the impact on to smaller particle as in rod mills.
