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.

Test sieves are an efficient, productive, and economical means of characterizing the gradation of dry granular materials. However, the sieving method is not without limitations. If obstacles seem to be making it difficult to produce accurate, repeatable results for finer sizes, Sonic Sieving may be the answer.

Do you know when a spinning riffler or rotary sample divider should be your go-to sample divider for the most accurate representative samples?

Testing sieves are not a one-size-fits-all product in materials testing. They should be selected based on application, compliance standards, sample composition, level of precision required and more.

Proper sieve shaker selection saves a considerable amount of time in the lab while improving accuracy and efficiency. Read our post about selecting the machine most suitable for your purposes.
