Inventing the Sonic Sifter: How a New Cafeteria Changed the Sieving Industry

July 01, 2020

<div><a href="/blog/history-of-sonic-sifter"><img loading="lazy" src="/Content/Images/uploaded/blog/2020/July/sonic-sifter-history.jpg" alt="Sonic Sieving History Article" style="display: block; margin-left: auto; margin-right: auto; width: 100%; max-width: 715px;" /> </a></div><p>Most materials have a lower size limit where sieving with a sieve shaker is no longer sufficient, and the agitation necessary for particle separation starts to break down and destroy some fragile materials. Particles in some substances resist separation and clump together due to electrostatic or moisture issues. For many years, these problems limited the effectiveness of measuring particle size by sieving. This article tells the story of how one man pushed back those boundaries.</p>
