Vibrating Screen Efficiency Calculations

An efficiency of 99% will equate to a significant loss of capacity. Efficiency is the ratio of undersize material in the feed that actually passes from the media to the undersize material that should pass from the media. This ratio is desired to be , however this is not possible due to the factors affecting the process.
