Anchor Impellers
Low Clearance Impellers
- The anchor impeller and the helical impeller are the two commonly used close clearance impellers.
- The diameter of the close clearance impellers is typically 90 – 95 percent of the inside diameter of the vessel.
- The shear near the vessel wall reduces the build up of stagnant material and promotes treat transfer.
- The anchor impeller is a radial flow impeller
- Helical impeller provides axial discharge of material by producing strong top to bottom motion
- Anchor blades may be used in combination with other types of impellers
