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.

Crusher adjustment (CSS) The closed side setting (CSS) defines the reduction ratio in cone crushers and has a significant effect on product gradation, capacity, and power draw. The closed side setting is measured from the bottom of the mantle to the bottom of the bowl liner at their closest point during the gyrating cycle.
