Polymer breakdown and subsequent compounding was historically accomplished on open roll mills although today these operations are almost always performed in an internal mixer. The open mill consists of two metal rolls which are jacketed for temperature control. These rolls turn toward each other at fixed separations and often at different speeds.

A mill apron which replaces the mill tray and consists a belt running under the nip rolls up to the top of the back roll the belt returns to the mill any powders powders which fall from the nip. 2. A stock blender which is a device for blending the rubber mechanically instead of depending upon the operator.

CT Internal Mixer CT Internal Mixer used for mixing or compounding and plastics. The mixer is for preparing plastic or rubber formulations by mixing or/and blending polymers and additives in a molten state. There are different factors to achieve a homogenous blend of the different raw materials.

Laboratory two-roll mill blending The pure elastomers and blends were compounded in a two-roll mill at 50 °C following conventional procedures in rubber technology. Firstly the elastomers were mixed to prepare a master batch where the other ingredients were added and mixed until they were completely dispersed in the rubber matrices.

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.
