Two roll rubber mill - Wikipedia

The rolls rotate towards each other, one faster than the other. The distance between the two rolls can also be adjusted by the operator. The opposing rotation directions and different speeds produces a combined shear and compression force on the material being mixed on the mill. With open roll rubber mills, the operator may also be in charge of ...

Roll Mill - an overview | ScienceDirect Topics

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.
