When is a Sieve Not a Sieve?

Posted by Amanda Ranowsky on Jul 17, 2014 5:00:00 AM

In our business, we use the word “sieve” to describe a piece of equipment that separates desired elements from unwanted material using a woven wire screen or mesh net. To others, “sieve” can mean something very different.

What is The Function of a Sieve Shaker?

Posted by Art Gatenby on Oct 17, 2013 4:56:00 PM

 

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.

Thought Your Moisture Measurement Challenge Was Complicated?

Posted by Art Gatenby on Dec 14, 2012 3:51:00 PM

As I've said many times, measuring Moisture Content, Surface Tension and Particle Size often confounds me. 

Moisture measurements are nothing compared to the measurements needed to check out the Universe. Came across this video and thought you'd fnd it interesting and fun.

Advances In Sieves: Sieves Able to Strip Molecules From Fluids

Posted by Art Gatenby on Nov 19, 2012 2:32:00 PM

Sieves make understanding the world around us not just possible, but also easier.

And with the advancement of sieves, not only are we able to separate dry particle, but also sift molecules from fluid as well. With molecular sieves developed by MIT, we can now strip a molecule’s individual parts gives us a better understanding of how things come together and work, such as diseases or even DNA.

Sieve Calibration Is the Holy Grail !

Posted by Art Gatenby on Sep 11, 2012 1:11:00 PM

Yes Harry, there is a Santa Clause. Or, more specifically, there really is a Holy Grail for ensuring consistent particle size analysis. 

If you’ve been following along, you know it was proven by Pequeño and his family of 150 micron particles who tried to bust our friend Harry’s quality control by attempting to slip through the mesh in Harry’s test sieves and defeat sieve certification.

(If you missed this drama, check out previous posts in the Holy Grail series.)

Now that we have indeed confirmed that, yes, sieve calibration really is the Holy Grail that sieve testers have been looking for, let’s get to work and dive a little deeper. Let’s examine some methods of sieve calibration.

Is Sieve Calibration Really The Holy Grail? Episode IV

Posted by Art Gatenby on Jun 18, 2012 4:01:00 PM

You may remember Pequeño and his family of very small 150 micron (150µ) particles being very determined to defeat sieve certification.

Is Sieve Calibration Really The Holy Grail? Part III

Posted by Art Gatenby on Apr 12, 2012 1:12:00 PM

We continue to search for answers to the question "Is Sieve Calibration Really the Holy Grail?" As promised,we present Episode III of the Pequeño saga. You may remember him as a very small (150-micron) particle with many similar-sized family members who are determined to defeat sieve certification.
