This week’s photo shows pellets on a sieve. Sieves, made up of a circular, metal frame, with a screen-like wire mesh in the bottom, are used to measure particle size distribution. A variety of sieve sizes can be found in the FEECO Innovation Center, each with a different-sized mesh to measure granules according to standardized sizes.
Sieves are an important tool at FEECO, helping lab technicians to measure how much under-, over-, and on-size pellets a process is producing. Additionally, they help to measure pellets of an unknown size, as well as confirm that a process is producing pellets within a desired size range.
Referred to as a sieve analysis, this is just one of several tests that lab technicians prepare when measuring an end-product’s characteristics. They also measure:
-
- Bulk density
- Flowability
- Crush strength
- Moisture content
- Abrasion and hardness
A sieve analysis, as well as the tests noted above, all help confirm the overall agglomeration process, and ensure that customers are getting the precise pellets they request.
