Abstract: PVC (polyvinyl chloride) is a solid plastic made from vinyl chloride. It is made softer and more flexible by the
addition of phthalates and bisphenol-A PVC is used to make pipes, sliding, medical devices and automobiles parts etc. The
PVC mixtures are used for mixing, drying, stirring and cooling of plastics for a daily usage. The temperature of the PVC
mixture is maintained around 120ºC and mixing the different chemical powders uniformly. The high speed stainless steel
mixer blades are used in PVC mixer. These blades are arranged in 3 series with different angles. Blades angle play an
important role for uniform mixing. The aim of this project work is to increase blade efficiency by designing a mixture blade
with new profile and material. In this work, the modeling of the blade will done using CATIA software package and analysis
viz., static, dynamic and model analysis will be carried out using ANSYS software package. The proposed new design ensures
longer life and uniform mixing of PVC elements in lesser time.
