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.

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).

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.

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.

The primary purpose of a sieve shaker is to provide motion to a sample in a test sieve.
An effective sieve shaker creates a motion that presents all the particles to all of the sieve openings and assists particles in passing through. This requires both rotary and vertical motion.
This process seems simple enough, but let's not be taken in.

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?”
