Jim, the Secret Agent, and the Machine That Changed Everything

Posted by Amanda Ranowsky on Oct 29, 2013 12:03:00 PM

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.

How Do I Set Up A Bostwick Consistometer?

Posted by Art Gatenby on Oct 23, 2013 8:30:00 AM

 

We get the same two questions almost every week about the CSC Bostwick Consistometer:

             1) What angle do I use to set it up?

             2) How do I level the Consistometer?

The principle of the CSC Bostwick Consistometer is based on the slump cone. In this procedure, a cone is filled with the material to be tested. It is then set on a level surface with the open area facing downward. The cone is pulled away and after a fixed time, the amount that the material slumped is measured.  The thicker the material, the less slumping occurs.

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.

What Can I Use To Get The Moisture Content In My Product?

Posted by Art Gatenby on Oct 3, 2013 5:36:00 PM

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.
