Particle Distribution Analysis

Quality control and continuous process improvements assure every bag is consistently uniform-including particle size.

Particle sizes are defined by the number of openings per square inch. We use "U.S. Standard" Mesh, so when you see the number in either column "pass" or "retained," it means there are that number of openings per square inch. Try counting the number of openings per square inch in a window screen and that is the mesh size.
