Sieving: how does it work? ● Powder passes through a screen that retains the particles with a bigger diameter (contaminants). ● The choice of the right mesh size of the sieving screen is very important and usually requires some compromise: o A finer mesh grants a higher-quality sieving. o A bigger mesh allows larger powder throughput. ● Different sieve technologies are available to fulfill various application needs: o Vibratory sieves are the easier solution, robust and reliable. o Ultrasonic sieves use higher frequency vibrations and can consequently process higher powder quantity with a small...
