Engineered Surfaces to Extend Service Life and Performance

Continuous Mixing Rotors

Continuous mixers provide high intensity mixing of viscous materials and allow the incorporation of fillers in compounding applications. These are counter-rotating, non-intermeshing twin rotors that often feed a hot extruder downstream.

The leading edges of mixing zones are weld protected with cobalt based Stellite hard facing and hard chrome plating on the entire surface.

Our C1000 tungsten carbide has been used as chrome replacement in aggressive applications.  C1000 doubles the working life of rotors compared to hard chrome plating.  We apply a minimum of .010” to .015” (.25 - .38 mm) thickness with a 16-32 RMS (.2-.4 Ra) surface finish after coating. 

C1000 has become an industry standard where aggressive processing is planned.
