Question

Which of the following agitators having a large blade area, rotating at slow speed is used for mixing high viscosity liquids (> 50000 centipoise) ?

Accepted Answer

Helical screw. Helical screws are designed for mixing very thick liquids because their large blade area and slow rotation provide good bulk movement.
