  • Single-Stage or Two-Stage Mixing? Rubber & Tyre

    Mar 02, 2015· Have you encountered the often dilemma, "Should I do single-stage or two-stage mixing for my compound; which machinery to use?” do not be surprised! You are not alone. Single-stage mixing is considered for productivity reasons (and cost-effectiveness). While Two-stage mixing gives a better dispersion of the finer size blacks. And interestingly, for some compounds

  • Dump Extruder Rubber & Tyre Machinery World

    Mar 02, 2015· Most experts feel two-stage mixing, with short time spans for each of the mixing stages, is helpful. 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.
