Figure 1a shows the schematic diagram of a four high stand rolling mill with the metal strip passing through the work rolls which are supported by backup rolls. It is assumed that the physical contact between work roll and backup roll can be modeled as springs, as shown in Fig. 1b. The damping between them is assumed to be negligible.

Tubular Rod Mills. In Mineral Processing Design and Operations (Second Edition), 2016. Rod Mill Charge. Rod mill charges usually occupy about 45% of the internal volume of the mill. A closely packed charge of single sized rods will have a porosity of %. With a mixed charge of small and large diameter rods, the porosity of a static load could be reduced even further.

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 ...

The roll rotates to pull and simultaneously squeeze the strip between them. The strip is rolled in several passes either in a reversing mill or in a tandem mill. Each work roll is supported by a backup roll of larger diameter. As the strip passes through the pairs of work rolls in each pass, the thickness is successively reduced.
