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.

The CSC Sieve Analyzer
The CSC Sieve Analyzer was designed to deliver a record of a sieve test results, eliminate operator error and significantly reduce the time to process and calculate these results.

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.

Break the Curse of Particle Size Calculations
Every now and then I’ve had to calculate the results of a sieve test: I’d get the sieves and sample loaded on the shaker, run the shaker, then realize I’d have to start over because I forgot to get the empty weight of each sieve. Or I’d have to carefully brush out the sample onto a balance.

Chapter One:
Jim’s life was dull. So, so dull. He spent his days surrounded by piles of sieves – his glamorous job was to calculate the ratio of particles left in the sieves of each stack after a sample of his company’s product was run through the stack using a sieve shaker. It was a job much like the one his cousin Hiram had, although he seemed to remember hearing that Hiram had found an easier way to do it.

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.
