Because the crusher is installed inside the mining pit, the trucks transport the minerals to the crusher at a shorter distance. Also, in this scenario, the trucks do not transport the crushed minerals to the processing plant, but the materials are transported by the conveyor directly from the in-pit crusher to the processing plant.

Selection of the optimum in-pit crusher
Using an in-pit mobile crusher can reduce the haulage costs, but due to high initial investment cost, this option has not been considered. Instead, changing the location of the crusher-screening plant during the operational period by uninstalling and installing the plant has been studied. Utilizing the crusher at a stationary position without ...
