A major producer of silicone compounds is using a Ross MegaShear UltraHigh Shear Mixer for processing their silicone gels. Previously, it took two passes through their three roll mill in order to completely disperse silicone polymers into a silicone or hydrocarbon solvent. Simulation trials at the Ross Test Development Center confirmed that ...

the geometry of the metal boundaries. In tworoll mills (Chapter 4) the geometry is the simple symmetry of parallel cylinders. With internal mixers (Chapter 5) and continuous mixers (Chapter 6) the geometry is more complex. Yet the same kind of fl uid mechanical analysis can be used for all types of mixers.

Two nylon coated cheek plates will avoid silicone rubber to get contaminated during the mixing process by picking up dirt and gear grease from sides of rolls. The gap between rolls should be adjustable and one roll should rotate faster than the other with a :1 to :1 ratio. The above Figure shows a schematic side view of a tworoll mill.

Mixing rubber compounds on a tworoll mill is common in the following situations: 1. Firstpass mix is accelerated, typically by a fabricator, as part of the preparation for molding, calendering, etc. 2. Small batches of specialty compounds are mixed. 3. Compound is accelerated on the mill after being dropped from an internal mixer. 4.

Rubber compounding was performed on a tworoll mill (Lab Walzwerk MT 6″×13″, Rubicon, Germany) in a threestage process. In the first stage, the rubber was mixed with zinc oxide, stearic acid, CB, and Struktol or IPPD. Then the rubber/MLG masterbatch was added to the rubber compound in the second stage.

Natural rubber, which is harvested from a rubber tree, hevea brasiliensis is the base for many rubber compounds made using a two roll rubber mill. Rubber trees are tapped to remove the latex that is stored in their trunks. This material can then be mixed with additional ingredients to create rubber.
