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.

History of rubber mixing. Posted on August 20, 2010 by jainthomas. Early compounding took place either in single rotor machines such as Hancock's Pickle, or on two roll mills. The first use of the two-roll mill was in the 1830s in the USA. Hancock's Pickle was patented in 1837, although models had actually been in use from the early 1820s .
