Abstract

Uniformity of mixed rubber in an internal mixer equipped with three longโ€type rotor sets was investigated. After mixing butadiene rubber with ZnO powder for a certain period of time, a small amount of the mixed rubber was taken out from two points in the mixer: the center point of the reservoir and the side point of the sickleโ€shaped zone on the rotors. The concentration of ZnO in the sampled rubber was measured by the atomic absorption analyzer to know the dispersion of ZnO into the rubber. The twist direction and helix angle of rotors, and the position of ZnO powder incorporation, affected the uniformity of mixed rubber. ยฉ 2004 Wiley Periodicals, Inc.

## Abstract It is well known that blade geometry significantly affects the performance and efficiency of partially filled internal mixers. Intermesh type blades with very long tips are regarded as effective alternatives to almondโ€shaped blades used in more traditional tangential rotor mixers. Howev

## Abstract Laminar flow and mixing of a Newtonian fluid are characterized in a fourโ€element Kochโ€Glitsch SMX static mixer. The computational analysis on a fine, unstructured mesh containing more than 3.5 million tetrahedral elements led to highโ€resolution numerical data for velocity and pressure.
