• Helical mixers are capable of operating over a wide band of viscosities, ranging from low-viscosity liquid to highly viscous materials up to 4 million cP.
  • These mixers have major advantages over anchor mixers because of their ability to generate strong top-to-bottom motion even with viscous materials.
  • To improve heat transfer through the jacket, wipers and scrapers can be attached to the outer periphery ribbon flights.
  • Helical mixers can be formed to fit in conical-bottom tanks, where the ribbon flights force the material to the bottom discharge, thereby facilitating greater yield from each batch mix.
  • Helical mixers work efficiently with heavy pastes as well as with flowable powders. A helical impeller is shown in Fig
