About Multi-screw Extruders

It is common knowledge that the advantages of multi screw extruders lie in the intermeshing section - the

apex.

The apex is the base for the advantageous features of multi-screw extruders:

Dispersive mixing via elongational flow

Distributive mixing via stream divisioins

Surface renewal for degassing

Self-cleaning for fast change-over times

Hence it is quite obvious that increasing the amount of screws in te extruder is an excellent way to boost

the capability of the extruder. The RingExtruder with 12 screw shafts is a co-rotating multi-screw extruder

which was developed for challenging mixing and degassing applications.

Your Benefit

Superior dispersive and distributive mixing

Excellent degassing

Extraordinary temperature and residence time control

Reduced energy input and lower operating costs
