Compounding and testing All recipes were mixed upside down in a Werner & Pfleiderer GK 1,5E internal mixer with a subsequent run on an open two roll mill for proper dispersion. If more than 10 phr of plasticizer were used, the amount was split and added in two steps. After batch off and 24h relaxation time the com-
The Two Roll Mill for Plastic Material has fixed friction and speed which is laid for continuous working conditions. This machine is also available with the roll diameters of about 150 mm. These rolls are mainly driven by the geared AC Motor. This rear roll is usually driven by the spur gears for regular friction. The Modifications…
Mill roll heights. All new mill installations shall be installed so that the top of the operating rolls is not less than 50 inches above the level on which the operator stands, irrespective of the size of the mill. This distance shall apply to the actual working level, whether it be at the general floor level, in a pit, or on a platform.

6.2.4 Nanocomposite Preparation. Rubber compounding was performed on a two-roll mill (Lab Walzwerk MT 6″×13″, Rubicon, Germany) in a three-stage process. In the first stage, the rubber was mixed with zinc oxide, stearic acid, CB, and Struktol or IPPD.
plasticizer paste color dispersions DISPERSIONS OF COLOR PIGMENTS:continued 3 Rubber-bound color dispersions use an internal mixer or mill to grind the pigment agglomerates down to a usable size. But the nature of this type of equipment only allows the machine clearances to get so close. Thus aggregate breakdown stops at this point. Many ...

(d)Phr refers to the grams of plasticizer in the formulation for every 100 grams of PVC. Fluxing of the PVC fonnu1ations was conducted on a steam-heated, two-roll mill. The front roll of the two-roll mill was operated at approximately 1.33 times the rpm of the back roll. Both rolls were heated to 340°F.
high standard of maintenance inspection and testing are essential. BS EN 1417 Plastics and rubber machines — Two-roll mills — Safety requirements provides details for the performance criteria for the Lunn bar and braking system. This includes a requirement for automatic roll separation and reversal on operation of the Lunn bar.

The rolling mill is equipped with a walking beam furnace with a capacity of 125 tons per hour. Blooms are de-scaled after exiting the furnace, and then proceed through a five stand roughing mill, a six stand intermediate mill, and an eight stand finishing mill. Dimensional control is maintained by optical laser gauges and manual micrometer checks.
