Selection of powder screening equipment
Thread Content
Question: For screening very light powdered materials with a particle size ranging from 200 to 325 mesh, should a mechanical sieve or an air-classifier be used? Which one is good? Equipment investment comparison? Cost comparison for operation? All participants receive a gift of wealth.
It should be an air classification machine. Take a closer look at “Selection and calculation of process equipment for powder engineering””
For powders of this grade, using mechanical screens can easily generate dust and the screening process is not smooth; therefore, air-classifiers are generally used. Since the mechanical sieve is not suitable, there is no need to compare equipment investment and operating costs.
Centrifugal air flow sieves are better; they are also being used currently. The density of our powder is around 0.3
