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.
