Commercial strip mills generally have a RSF of several thousand tons. Small mills in general, and certainly hobbist mills, are static. The roll gap is set and then the strip is fed into the mill. Commercial mills will have screwdowns that exceed the rated RSF so that the gauge can be adjusted with the strip in the mill.

Tools to achieve dispersion include three roll mills, ball mills and bead mills for the final dispersion. Three roll mills are most commonly in the production of screen printing, pad printing, UV, and glass/ceramic inks, since they are more viscous in nature. For liquid inks, other types of mills should be used since the solvent would evaporate ...

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.

Such roll gap profile control can be carried out on mills equipped with work roll crossing and by making use of a combination of roll axial shifting and asymmetrical rolling. In work roll shifting method, the aim is to make the strip thickness uniform and improve the flatness over a wide range of strip widths by shifting rolls of special shapes.
