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 1:1.25. Two roll mill mixing is also known as open mill mixing.

Two-Roll Mill Rubber Tyre Machinery World

27/04/2015  If you are using a 270 Liter Tangential Internal Mixer, you are engaging at least two units of 26″x84″ two-roll mills in the downstream section. Each 26″x84″ two-roll mill, requires around 180 kW (minimum) motor power – totaling to 360 kW (=180 x 2) only for the mills. For a similar capacity mixer, a TSS downstream will not seek more than 300 kW power

Rolling (metalworking) - Wikipedia

Roll forming, roll bending or plate rolling is a continuous bending operation in which a long strip of metal (typically coiled steel) is passed through consecutive sets of rolls, or stands, each performing only an incremental part of the bend, until the desired cross-section profile is obtained. Roll forming is ideal for producing parts with long lengths or in large quantities. There are 3 main processes: 4 rollers, 3 rollers

Rubber Compounding - an overview ScienceDirect Topics

Two-roll mills have been used for rubber compounding since the middle of the nineteenth century. Originally they were also used for mastication of natural rubber, to break down high molecular weight fractions. However, such breakdown is generally not desirable for synthetic elastomers, including fluoroelastomers, which are designed to have molecular weight distributions optimized for various

Rubber Compounding - an overview ScienceDirect Topics

The mill consists of two closely spaced parallel, horizontal rolls made from hard castings supported by strong bearings in a mill frame. The counter-rotating rolls are driven at different speeds to maintain a friction ratio of 1.05 to 1.25, transporting the rubber over the top of the roll to the nip area, then through the nip with small adjustable clearance (usually 2–6 mm) to subject the stock to high shear stresses.

mechanical engineering: Types of rolling mills

It is a special type of four high rolling mill in which each of the two working rolls is backup by two or more of the larger backup rolls for rolling hard in materials. It may be necessary to employ work rolls of a very small diameter but of considerable length. In such cases adequate of the working rolls can be obtained by using a cluster mill.
