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.

A question we get a lot is:

“How do I determine the moisture in my product?"

Of course, the answer is often “it depends”, and the method does depend on the chemical and physical composition of the product. There are several methods used to determine moisture content: Loss-on-Drying (also known as Weight Loss), Karl Fischer, NIR, and Radio Frequency.
