Extruder nonintermeshing counter rotating

Fig. 13.1. Different types of extruders, a) single screw b) co-kneader c) non-intermeshing, mixing mode d) nonintermeshing, transport mode e) counter-rotating, closely intermeshing f) co-rotating, closely intermeshing g) conical counter-rotating h) self-wiping, co-rotating.

Figure 5.14 Diagram showing the difference between (a) intermeshing and nonintermeshing as well as (b) co-rotating and contra-rotating or counter-rotating types of twin screw extruders. (Fteprinted from Ref. 20.)...

Counterrotating intermeshing twin-screw extmd-ers have the narrowest residence time distribution followed closely by co rotating intermeshing twin-screw extmders. Counter rotating nonintermeshing twin-screw extruders have the broadest residence time distribution.
