Description

Particle Size Conversion Table - Free download as PDF File (.pdf), Text File (.txt) or read online for free. This document provides a conversion table for particle size designations based on standard sieve sizes. It lists sieve sizes in inches, millimeters, and microns. Mesh sizes above 1/4 inch correspond to the sieve opening size in inches, while smaller mesh sizes refer to the number of openings per linear inch. The document explains that a "+" before the mesh size indicates particles are retained by that sieve, while "-" means they pass through, and materials are typically described as falling within that size range. It gives an example of a -4 +40 mesh designation meaning 90% of particles are smaller than 4.76 mm but larger than 0.420 mm.
