Apparatus for the treatment of non-homogeneous rubber mixtures.

摘要

1. A mixing and kneading apparatus in the form of an extruder screw for processing inhomogeneous mixtures, comprising a mixing section and a kneading section, the screw channels being inconstant in depth, characterised in that for processing inhomogeneous rubber mixtures the depth of the screw channels increases gradually and continuously from almost zero and suddenly decreases again to almost zero, so that a "chamber" is formed, in which the material being processed is set in rotation.
