ABSTRACT:
This invention provides in a continuously operating device having a mixing section comprising opposite-handed helical threads in each of the two relatively rotatable components which threads vary in cross-sectional area in complementary fashion so as to produce a layer-by-layer material transfer and shear working between the said components, that the said opposite handed helical threads in said mixing section complement one another substantially also in respect to their helix-angles to the extent that if one helix angle is between 0.degree.and 45.degree. the other is between 45.degree. and 90.degree., to bring about, viewed with respect to the shear-plane-area, a subdivision sufficient for the mixing and compounding requirement.
