Powder particle size known particle size. The particle shape is very complex, usually have a representation of particle size, particle size, particle size, sedimentation volume equivalent equivalent surface area of particle size of particles. The granularity is through the screen mesh size, with 1 inches (25.4mm) the number of mesh width of the screen mesh representation, so called "the number of"
In addition to screen more holes. That hole, it can be said at the same time for the screen by the particle size, the higher the number, the smaller the particle size, the standard sieve with standard vibration sieve machine can be determined accurately
Refers to the number of orders per square inch empty eye screen, 50 holes per square inch refers to the 50, 500 is 500, the higher the number,
