introduction of two roll mill

Two roll rubber mill Wikipedia

The two roll rubber mill is a machine used to process natural rubber into various compounds. Two horizontally opposed stainless steel rolls rotate in opposite directions towards each other at different speeds to mix the rubber and ingredients used to create the rubber compounds. Rubber being produced using a two roll rubber 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.

Mixing mills DEGUMA-SCHÜTZ GmbH

The two rolls of the rolling mill rotate in the opposite direction. For the purpose of mixing, one roll runs faster than the other one (friction). Therefore, shearing forces act on the rubber in the nip between the two rolls. In this way, the rubber is mixed. Structure of a mixing mill. A mixing mill consists of two rolls arranged in parallel

Rubber Processing Britannica

Rubber mills have two large horizontally opposed, closely spaced steel cylinders, up to 3 metres (10 feet) long, that are rotated slowly in opposite directions and at somewhat different speeds. Rubber is sheared and softened in the gap between the paddles and wall of the Banbury mixer and in the gap between the two cylinders in the roll mill.
