What is Screening Efficiency? — iBulk Solutions Pty Ltd

2013-1-3  Technically, screening efficiency is described as the comparison of the undersize material carried over the screening media and discharged with the oversize product in contrast to the input amount of undersize that was initially fed into the screen. This result is expressed as a percentage and given the term screening efficiency.

Screening is an important part of processing and is used to separate material according to its size. Material is typically fed to a single-, double- or triple-deck screen to make the required sizes. Screens can be considered the cashbox of the operation, because while crushers make the gradation, screens make the specification. Material must go through or over a specified size to
