Particle Size Monitoring - Innopharma Labs

Sieve analysis presents particle size information in the form of an S – curve of cumulative mass retained on each sieve versus the sieve mesh size. The most commonly used metrics when describing particle size distributions are D-Values (D10, D50 & D90) which are the intercepts for 10%, 50% and 90% of the cumulative mass.

Circle-throw vibrating machine - Wikipedia

A circle-throw vibrating machine is a screening machine employed in processes involving particle separation. In particle processes screening refers to separation of larger from smaller particles in a given feed, using only the materials' physical properties. Circle throw machines have simple structure with high screening efficiency and volume.
