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.

Not because they themselves are more efficient, but because conveyors are more energy efficient than trucks. Combining mobile and semi-mobile packages and coarse ore sorting – for example by rejecting waste rock after secondary crushing in the pit – can be a game changer. In-pit crushing and conveying can bring energy efficiency to …
