    What is Screening Efficiency iBulk Solutions Pty Ltd

    Jan 03, 2013 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.
