OPEN MILL MIXING ON TWO-ROLL MIL RUBBER

Jul 20, 2013 Mixing on 2-roll mill The mixing is often done on a two-roll mill (open mill). A mill consists of two horizontally placed hollow metal cylinders (rolls) rotating towards each other. The distance/gap between the mill rolls (nip) can be varied, typically between 2 to 20 mm.

Mixing mills DEGUMA-SCHÜTZ GmbH

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.

Introduction to rubber processing and safety issues

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

Two-Roll Mill Rubber & Tyre Machinery World

Apr 27, 2015 One school of thought advocate an open two-roll mill for second-stage mixing because the dispersion of the batch and the mastication is higher (than an internal mixer). Open mills, though slower, are safe for short scorch compounds. Depending on the presence or absence of alloy, the hardness of the outer working (chill) zone could be in the

Study of mixing efficiency in roll-mills. Free Online

Feb 15, 1996 Figures 10 and 11 show the volumetric distributions for the parameter [N.sub.s] and shear stress. These Figures indicate a broad distribution of flow regimes for the roll-mills. We looked at the influence of the friction ratio (ratio of the tangential velocities [U.sub.1]/[U.sub.2] for the two rolls) on the mixing efficiency of the roll-mills.
