safe procedure of two roll mill

Roll Mill an overview | ScienceDirect Topics

A two roll mill consists of two horizontally placed hollow metal rolls rotating towards each other The distance between the mill rolls can be varied and this gap is known as nip The speed difference between the rolls is called friction ratio and it allows the shearing action The back roll moves faster than the front roll; a common friction ratio is 1:125 Two roll mill mixing is also known
