Screening efficiency is calculated as the percentage of the undersize materials passing through the openings divided by the percentage of undersize in the feed. For example, if a screen is only 75 percent efficient, then 25 percent of the material within the desired product range is being rejected with the oversize material.

The process of screening falls under two categories namely (i) screening by stratification, and (ii) screening by free fall. In the case of screening by stratification, screening is carried out by building up a material bed on a screen deck. The material gets stratified when the motion of the screen reduces the internal friction in the material.
