Egan mixing section

Fig. 24. Dispersive mixing sections for use in single-screw extruders (a) blister ring, (b) Union Carbide mixing section, (c) Egan mixing section, (d) Dray mixing section [148]...

Another fluted mixing section is the Egan mixing section invented by Gregory and Street [47] see Fig. 8.67. 

A similar mixing device was later patented by Gregory [48]. The difference between this mixing device and the Egan mixing section is a constant depth in inlet and outlet channel and a concave channel geometry. Another similar mixing section was patented by Dray [49] see Fig. 8.68.
