Contra Rotary Mixer is an ideal mixer for the product of high
viscosity & density. It is suitable for thorough mixing/ blending of
tooth paste, grease & other viscous compounds.
Working Principle
The mixer consists of two different blades rotating clockwise and anti-clock wise simultaneously. It consists of two different shafts, one being solid and the other hollow. The solid shaft is provided with multiple paddle blades, which rotate in clock wise direction while the hollow shaft with anchor scrapper blade assembly rotates in anti-clock wise direction. Intimate & homogeneous mixing of products is achieved by contra rotary motion of two different blades & high speed homogenizer. Vacuum jacketed mixers are provided with vacuum pump, heating arrangement etc.

Inbuilt homogenizer with mechanical seal is provided with the bottom dished end for emulsification. It is a chopper type high shear emulsifier. The high shear action creates a forced product flow. The interchangeability of chopper blades is also possible to suit the mixing requirement of various viscous products. On-line homogenizer with specially designed filter can also be provided for re-circulation of the products.
  • Uniform mixing & homogenizing of the viscous products is possible because of the contra rotary motion with homogenizer & anchor blades with scraper assembly
  • No air contamination because of vacuum operation
  • No product contamination because of the sanitary design
  • Minimum residual product loss because of anchor scraper design & suitable sized bottom outl
  • The shaft seals are mounted above the product, so there is no possibility of contamination
