Particle Size Distribution

2016-7-7 · Particle Size Distribution This section discusses particle distribution. The finer sizes are called fine earth (smaller than 2 mm diameter) as distinct from rock fragments (pebbles, cobbles, stones, and boulders). Particle-size distribution of fine earth or less than 2 mm is determined in the field mainly by feel. The

AFM® Technical Information

AFM is manufactured as opposed to being quarried, the particle size distribution and shape can therefore be maximised to improve performance as a water filtration media. AFM has an optimised uniformity coefficient in order to maximise filtration performance without causing pressure drops or bed lensing effects.

Understanding & Interpreting Particle Size Distribution ...

All particle size analysis instruments provide the ability to measure and report the particle size distribution of the sample. There are very few applications where a single value is appropriate and representative. The modern particle scientist often chooses to describe the entire size distribution as opposed to just a single point on it.
