  • Static mixers are now used in all areas of chemical engineering. A characteristic feature of static mixers is that only the liquids or gases to be mixed are moved. In contrast to dynamic mixing systems, no stirring takes place, but pumps, blowers or compressors continuously convey the media to be mixed to the mixing tube, which with the Equipped mixing elements. Static mixers can be used in many applications such as mixing of pumpable liquids, dispersing and emulsifying intoluble components, mixing reactive liquids, mixing and homogenizing plastic melts, gas-liquid contacting, mixing gases, heat exchange of viscous substances and the use as residence time with narrow residence time behavior are used, to name a few key applications.

  • the plates must be positioned with countless welds, which can lead to increased corrosion.
  • the assembly of the plates is very time consuming and therefore costly.
  • This known device is used in particular for mixing in the laminar range. In the turbulent range, it is only partially usable because of its high pressure loss.
