Sieve Calibration Is the Holy Grail!

Posted by Art Gatenby on Oct 13, 2020 5:30:00 PM

Yes Harry, there is a Santa Claus. 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.

Can We Fix The Problems Of Sieve Certification?

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

All about sieve Calibration

We continue to search for answers to the question "Is Sieve Calibration Really the Holy Grail?Pequeño, you may remember him as a very small (150-micron) particle who has many similar-sized family members. They are determined to defeat Brad and his Sieve Certification.

Will Certification Lead To The  Holy Grail Of Sieving?

Adventures of Pequeño

This is another Adventure of Pequeño: The 150 Micron Particle, I wonder why I get myself into these fantasies. However, once I start I feel constrained to press on.

In an earlier encounter, our little friend Pequeño, was on a determined quest to make it through sieves -- particularly those through which were said be too small for him to pass. In this scenario, Pequeño along with some of his family and friends -- all small particles about 150 microns in size -- are on their way to a sieve test.

Is There a  Holy Grail of Sieve Analysis?

Holy grail and Sieve Calibration

Sieve calibration is the final step in determining whether processes yield suitable end results. In other words:
  • Is your concrete going to be strong enough?
  • Will you chocolates taste right?

  • Will your washing powder flow and dissolve as advertised?

  • Is there dangerous residue in your pill stock?

  • Will the “frack sand” keep the fractures open?

  • Is my salt of the correct grade?

If these are not correct, serious consequences could result (e.g. spoiled product, returned batches, rework or scrap).

When is a Sieve Not a Sieve?

Posted by Amanda Ranowsky on Dec 18, 2019 4:45:00 PM

In our business, we use the word “sieve” to describe a piece of equipment that separates different sized particles  using a woven wire screen. To others, “sieve” can mean something very different.

Is Test Sieve Certification All You Need?

Posted by Art Gatenby on Oct 29, 2015 1:45:10 PM

For several years, people in the test sieving business have been grousing about the difficulty of making sure that a test sieve certification is what they need. Anyone who is working with close tolerances in the smaller particle sizes, like 300 microns and smaller, have serious issues in matching results from test sieve to test sieve.

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.
