A Sieve Shaker's Passing From Noise To Quiet

Quiet Sieve Shakers

Recently in a quiet, reflective moment, I recalled my first work with sieve shakers. Horizontal motion with tapping was the basic shaker design. The Ro-Tap® was King, and there were few alternatives. Different shakers for special applications, such as the Mary Jane and one that was hung from the ceiling, were the exception.

How Do You Analyze Small, Micron-Sized Particles?

Posted by Art Gatenby on Jan 30, 2014 2:00:00 PM

Sieve testing, as I have stated many times, is the Cinderella of particle size analysis because it delivers more value than expected from something that’s so easy to use and relatively inexpensive. However, the problem with standard sieving techniques using wire mesh sieves is that they begin to exhibit accuracy problems in the lower micron sizes.

What is The Function of a Sieve Shaker?

Visitors to our web pages often arrive with the question, “What is the Function of a Sieve Shaker?

The simple answer is “to expose the particles in a sample to all the openings in each sieve in a stack”. A sieve stack is the result of fitting each sieve to be used in a given particle size analysis into the one above. The sieve with the largest mesh holes is at the top with each subsequent sieve of a tighter mesh size than the one above it.

Is Particle-Size Analysis Boring? Trivial? Amazing? Exciting? Vital?

When I tell people at cocktail parties that we specialize in Particle-Size Analysis. I usually get a polite response of ------ “OH !!,”   which translates to “So who cares?”
