Particle Size Conversion Chart Williams Patent Crusher

As the mesh size increases, the particle size decreases to create a finer material. Mesh size is not a precise measurement of particle size, but it is a fair estimation. A micron, also called a micrometer, is the metric unit of measurement for 0.001 millimeters. It is used here to refer to the thickness or diameter of the reduced material.
