Viewing the crushing plant as an industrial process clearly shows that it is not the individual machines that need to be optimised. In fact, just optimising a machine will not necessarily be beneficial for the crushing plant. Automating the adjustment of the plant is therefore crucial to ensure that the plant is operating at its peak performance.

The reduction ratio is driven by the Crusher Close Side Setting. The actual minimum safe closed side setting of a crusher will vary somewhat, for any given crushing machine, depending upon the character of the material, the amount of fines in the feed, and whether the crusher is being operated under choke-feed or regulated feed conditions. It is possible, when all conditions are favourable, to
