Mesh is a commonly used term across multiple industries to denote the material particle size or sieve aperture size. It serves as a core metric for gauging the fineness or coarseness of powdered or granular materials, and mesh is applied in sieving, grading, and quality control processes.
Mesh is defined as the number of mesh openings within a 1-inch by 1-inch area. A material is classified under a specific mesh if it can pass through a sieve with that corresponding number of openings per square inch. For example, 200 mesh indicates that the material can pass through a sieve with 200 openings in a 1-inch by 1-inch area. By extension, a higher mesh signifies finer particle size of the material, whereas a lower mesh indicates larger particle size.
