Mixing typically is performed in an internal batch mixer. The internal mixer contains two rotors which shear the rubber mix against the wall of the vessel. Internal mixing is performed at elevated temperatures up to approximately 330oF. Once mixed, the rubber is discharged from the mixer and processed into slab rubber or pellets.
Rubber Technology is the subject dealing with the transformation of rubbers or elastomers into useful products, such as automobile tires, rubber mats and, exercise rubber stretching bands. The materials includes latex, natural rubber, synthetic rubber and other polymeric materials, such as thermoplastic elastomers. Rubber processed through such methods are components of a wide range of items.

shearing rubber. Mixing can be either by internal mixing or external/open mill mixing which have very different safety problems. Internal mixing (eg. Banbury or Intermix mixers) The compound ingredients are fed into an enclosed mixing chamber via a feed hopper and mixed by the shearing action of two winged rotors and the walls of the mixing ...
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 ...
