The 28mm diamond mesh on the top deck of the ST4.8 was replaced with a 30mm square mesh which marginally improved throughput on this deck. The bottom deck also had a 5mm piano wire replaced with a more conventional 10mm square mesh which helped to control the final product and made sure there were no large pieces of flaky material finding its way into the product stockpiles. And finally, a controversial decision was made. They would “split the train”. This essentially meant that most of the material would be subject to double handling, an issue not taken lightly by anyone involved in crushing and screening due to the high costs involved. A safety stockpile was created by the first half of the train which consisted of the mobile jaw, scalper and cone crusher (LT106, ST2.8, and LT200HP), which meant that the second train of an additional cone crusher and triple deck sizing screen (LT200HP Short Head and ST4.8) always had material to crush, even when the first mobile train was not available. When the second section of the mobile train would have to be stopped, the first section could carry on crushing material to be stockpiled and then fed into the second section of the train.
