The number of rolls, the roll diameter, the roll spacing, and the stability of the entire machine, especially the leveler rolls support, are decisive criteria in leveling. The number of rolls depends on the material thick-ness and the yield point. In principle, a large number of rolls – up to 21 – are used for thin material; while

4.2.3.1.1 Roll Mills. The roll mill is the simplest batch mixing equipment. The principal design consists of two horizontal rolls, usually of equal size, arranged side by side and rotating toward each other at different speeds. The ratio of the peripheral speeds of the rolls, known as friction ratio, ranges from 1 to 2 but is usually around 1.2.
