Blog posts tagged with 'Particle Sizing'

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.

Concluding our two-part series on aggregate characteristics. Find out how shape, size, and specific gravity play a part in determining the effectiveness of aggregates in construction projects.

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.

In this blog, we explore the two primary forms of soil classification for geotechnical purposes. Visual and laboratory classifications of soils are two distinct procedures that are part of a complete soils investigation.

In part 3 of this three-part series, we’ll cover the procedure for effective particle size distribution of coarse aggregates, useful equipment and testing tips.

In part 2 of this three-part series, we’ll outline a sieve analysis of coarse aggregate including proper preparation of bulk field samples for lab testing and necessary equipment and tips.

When dry sieving isn’t sufficient for producing an acceptable degree of separation between individual fractions of a sample, it’s time to try wet sieving. This blog post covers the importance of wet sieving, when it is best used, and recommended equipment for various procedures.

In Part 1 of this thee-part series, we’ll cover sieve analysis of coarse aggregate, beginning from gathering samples at a job site, including tips and necessary equipment.

Gilson's Screen Shakers offer years of service when maintained properly. This blog post covers the steps you can take to ensure you get optimal use out of your Screen Shakers.
