It can be used to have thicker rolls of paper, being the more productive in the color as a paper roll mill. However, thicker rollers can also be used for different thicknesses.
A three roll mill is also useful in its design because it allows high-quality steel materials to reduce the thicknesses of any rolling product. Hence, a three roll mill is typically used for fabrication and manufacturing of high-quality steel, such as aluminum or stainless steel because it is relatively resistant to wear and tear.
