The XRD results show that there are two major phases exist in bulk α-Fe(Si,Cr) solid-solution: the ordered phase (DO3) and the disordered phase (A2), and a DO3-to-A2 phase transition occurs in the milling process. After 80 h of milling, the grain size decreases from 50.1 to 33.7 nm, and the internal strain increases from 0.079% to 0.485%.

Rawmill - Wikipedia

A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill.The raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a large effect upon the ...

How to Install Asphalt Milling for a Driveway | Hunker

Asphalt millings are recycled in almost every new asphalt mix that is produced. Not all of the milled asphalt is reused in new asphalt. Most projects limit millings to no more than 30 percent of the volume of the new mix. There are other uses for millings such as on driveways or on less traveled roads.
