Jul 23, 2012 · After evaporation of the solvent, the nanocomposites were passed through a very small gap in a threeroll mill mixer (Exakt 80E, Exakt Technologies) for final high shear mixing . The gaps between the rolls varied in three batchwise progressing steps (10 passes each) with three different gaps at 25 μm, 10 μm and 5 μm, respectively. The speed ...

As a final mixing step, the whole mixture was passed twice through a threeroll mill (Exakt 35/50, Norderstedt, Germany), achieving a total residence time of one minute. Once the nanocomposite solution was obtained, the films were casted as previously described for the pristine PVAm.

Aug 06, 2019 · A three roll mill is composed of three horizontally positioned rolls rotating at opposite directions and different speeds. When material is passed through the first nip, between the feed roll and the center oil, it is subjected to high shear force resulting in mixing, refining, dispersing and/or homogenizing of the material.

The ribbon blender consists of a relatively long troughlike shell with a hemispherical bottom. The shell is fitted with a shaft on which are mounted spiral ribbons, paddles or helical screws, alone or in combination. These mixing blades produce a continuous cutting and shuffling of the powder by circulating the powder from end to end of the trough as well as rotationally.
