SIZE REDUCTION AND SEPARATION (4TH SEM MINERAL ENGG.) MODULE-I Laboratory screening: Mesh number Mesh number is the number of apertures per linear inch. Sieves are designated by mesh number. Mesh size is the size of an aperture i.e. the distance between two parallel wires. As mesh number increases, mesh size decreases.
