What Is A Rolling Mill? 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 and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled.

A roller mill requires 15-40% less energy to produce a 700 micron particle size than a hammermill, but if grain types are to be changed frequently, the roller mill will need to be adjusted for each grain. A roller mill will produce grain with a more uniform particle size (less fines and large particles) than a hammermill.
