A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product. The metal changes its shape gradually during the period in which it is in contact with the two rollers.

Rolling mill consisting of three rolls or known as 3 high rolling mill is typically used for performing multiple reduction passes by wrapping material around the center mill roll and performing another reduction on the opposite mill roll pair. 3 high mill can also be used with varying mill roll sizes to induce a specific percentage of reduction of material on a single side of the work piece.
The four high mill uses this principle with two smaller work rolls each supported by a larger backing roll. figure145 the cluster mill, or sendzimir mill, uses a small work roll backed up by many other rolls.
