Daily Question: [2011-11-10] The slurry tank mixer uses two layers of impellers; are the diameters of these impellers the same?
Thread Content
The coal slurry tank mixer is equipped with two layers of impellers; are the diameters of these impellers the same? Is it the same good, or different good?
The slurry tank mixer features two layers of impellers, which are of different types
It’s better if they’re not the same; this way, the resistance is lower and the mixing effect is better
It’s good to have two layers of slurry with different diameters.
So, is the diameter of the upper blades larger or that of the lower blades? Is there a ratio between the two?
It should be the same; why would it be different?
Two layers of blades, with different blade diameters; it’s good that they are different
What’s wrong with being the same? We are the same; it’s also convenient for producing spare parts. Pay less attention to other theories.
In a slurry tank, suspension is achieved by requiring a high discharge flow rate; the diameter of the impeller and its rotational speed are the key factors determining this discharge flow rate. As long as the discharge flow rate required for suspension is met, there’s no need to worry about whether the impeller diameters are identical.
It doesn’t matter whether they are the same or not; of course, when the height-to-diameter ratio is high, it is recommended to use blades of the same diameter. On the other hand, for energy-saving reasons, a design with a smaller upper part and a larger lower part can also achieve uniform suspension. Hehe, it depends on what kind of tank you have.
For the agitator blades in the coal slurry tank, when looking down along the axis, do the two layers of blades overlap?
