Multiple blade paddle agitator is used for mixing high viscosity liquids/paste in which the paddle diameter is commonly 0.8 times the tank diameter. However, the width of the blade is in the range of ______________ times the paddle diameter?
Correct answer: A. 0.1 to 0.25
- A. 0.1 to 0.25
- B. 0.3 to 0.5
- C. 0.5 to 0.6
- D. 0.65 to 0.80
Explanation
For high-viscosity mixing, a multiple-blade paddle is broad enough to move paste effectively, with blade width commonly about 10 to 25% of the paddle diameter. The smaller ratio is unsuitable for strong bulk movement, while the larger ratios are unnecessarily wide.
