Background
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. The fraction passing through the screen openings is called undersize and the fraction remaining on the screen is called oversize. Screening is generally applicable to coarser material, i.e. material greater than 0.5 or 0.25 mm. The finer (less than 2 mm) is classified by the different particle sizes depending on the sedimentation speed of the material in the medium (water or air). 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, when classifying, the specific gravity and shape have a remarkably high influence
