Sieve Calibration Is the Holy Grail!

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.

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).
