The speed of the two rolls is often different [41–46]. The back roll usually turns at a faster speed than the front roll, this difference increases the shear force. The difference in roll speeds is called friction ratio, which is dependent upon the mill's use. For natural rubber mixing a ratio of 1:1.25 for the front to back roll is common .

how these occur in actual mixers. The primary difference between types of mixers is the geometry of the metal boundaries. In two-roll mills (Chapter 4) the geometry is the simple symmetry of parallel cylinders. With internal mixers (Chapter 5) and continuous mixers (Chapter 6) the geometry is more complex.
