Mill (grinding) - Wikipedia

W R = c R ( 1 d E − 1 d A ) {\displaystyle W_ {R}=c_ {R}\left ( {\frac {1} {d_ {E}}}- {\frac {1} {d_ {A}}}\right)\,} with W as grinding work in kJ/kg, c as grinding coefficient, dA as grain size of the source material and dE as grain size of the ground material. A reliable value for the grain sizes dA and dE is d80.

Rolling (metalworking) - Wikipedia

In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization …
