• Anchor mixers are among the more common types of high-viscosity liquid mixers.
  • Anchor-shaped impellers are used for liquid viscosities between 5000 and 50,000 cP.
  • The swing diameter of the anchor is generally 90 to 95% of the mixing vessel.
  • There is low clearance between the impeller and the internal wall of the vessel.
  • Anchor impellers are preferred when heat transfer through a jacket is desired along with good mixing.
  • Scraper arrangements or wipers may be provided to remove material deposited on internal walls of the vessel, further improving the transfer of heat.
  • Anchors are commonly used in crystallization reactors.
  • Speeds range from approximately 5.5 to 45 rpm
  • Impeller diameters range from 600 to 3000 mm. An anchor impeller is shown in Fig.
