The Sonic Sifter will successfully separate samples down to 5 micron in as little as one minute,sometimes less, with consistent repeatability.The sieving action, which can be varied for different densities and textures of material, is unique. A vertical column of air is made to oscillate through a sieve or set of sieves. The motion of the air alternately lifts the sample and then assists it through the sieve apertures.The oscillation amplitude is variable. A vertical mechanical pulse may also be applied to the sieves at regular intervals to break down any clustered particles and help eliminate any blinding of the apertures.
An important feature of the Sonic Sifter is that it causes very little attrition of the sample and virtually no screen wear.
