Polybutadiene rubber is seldom used alone, but is instead mixed with other rubbers. Polybutadiene is difficult to band in a two roll mixing mill. Instead, a thin sheet of polybutadiene may be prepared and kept separate. Then, after proper mastication of natural rubber, the polybutadiene rubber may be added to the two roll mixing mill.
This refers to mixing operations using horizontal two roll mills. The operator (usually known as a mill man) places the various ingredients in the nip formed between the rolls and mixes the compound by cutting it off the rolls and re-feeding it into the nip until all the ingredients are added. Mills are used not only for blending of
Mills. Where a mill is so installed that persons cannot normally reach through, over, under, or around to come in contact with the roll bite or be caught between a roll and an adjacent object, then, provided such elements are made a fixed part of a mill, safety control devices .

Apr 27, 2015· Let me help you with a quick back of the envelope calculation. 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.
Two-roll Mills Every mixer must provide two basic functions, both equally important-acceptable dispersion (intensive or dispersive mixing) and high uniformity (extensive or distributive mixing). The equipment used most often by the rubber technologist is the two-roll lab mill-a device for preparing small quantities of mixed compound.

An elastomer is a polymer with viscoelasticity (i.e., both viscosity and elasticity) and has very weak intermolecular forces, generally low Young's modulus and high failure strain compared with other materials. The term, a portmanteau of elastic polymer, is often used interchangeably with rubber, although the latter is preferred when referring to vulcanisates.

SPEAKER NOTES. Introduction ...
Typically, a two-roll mill is used for the blending process. If the elastomer stock has been stored in the cold, warming to room temperature before unwrapping could help avoid condensation on the elastomer, which might cause voids in molded or extruded parts.
Aug 01, 2006· Just as with mill bagging, discussed above, some stocks will also go to the back roll of a two-roll mill. Usually, adjustments in mill temperature(s), mill nip distance, friction ratio or even changing to another mill size, will commonly correct this problem (ref. 77). Part II will appear in the September issue. References (1.)
