The sigma blade profile is shown in figure 1.
In mixers handling very viscous materials, it is necessary topromote both lateral and transverse motion of the material. Thegeometry and profile of the sigma blade is designed such that theviscous mass of material is pulled, sheared, compressed, kneaded,and folded by the action of the blades against the walls of the mixertrough. The extent to which this happens depends on the action ofthe blades – tangential or overlapping and the ratio of the speed ofrotation of the blades.The helix angle of the blade can be modifieddepending on the required shearing.
