Roll Mill - an overview ScienceDirect Topics
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.

Roll mill for reduction of moisture content in waste ...
Moisture reduction is essentially accomplished in a two roll mill whereat the sized material is subjected to severe pressures for moisture removal with the particle taking flake form. The flake may be used as a furel source having a high bulk density or be subjected to still further processes, for example gasification, cubing, pelletizing, etc.

2021-8-9 The simplest type of mill vibration is found in all mills. It is a forced vibration due to roll eccentricity and so occurs at roll rotation frequencies. These frequencies are usually lower than any of the resonant frequencies of the mill stand. Therefore, gauge variation is a result of the stiffness response of the mill
