Sieving is a method of separating particles of a particle group according to the particle size, specific gravity, chargeability, magnetism, and other powder properties. The operation of dividing the mixed material with different particle sizes into different particle size grades by using a perforated screen surface is called screening. Screening is generally applicable to coarser material, i.e. material greater than 0.5 or 0.25 mm. And the finer is classified, wherein the classification is an operation of dividing the materials into different particle sizes according to different settling speeds of the materials in the medium. The particle groups are mainly separated according to the particle sizes or the volumes during screening, and the influence of the specific gravity and the shape is small; however, the specific gravity and shape of the sample are significantly affected by the classification.
