The preliminary roller mills have a structure made of steel, with a very rigid profile. The roller bearings (widely dimensioned for the maximum loads foreseen) are assembled on conical bushes and allow for an exact adjustment of the fitting's clearance/gap. The preliminary roller mills' range comprehends cylinder diameters from 800 to 1200 mm

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 temperature, then the process is known as hot rolling
