Mobile in-the-pit crushing with Lokotrack and Lokolink
In order to make the right decision, it is necessary to compare the total cumulative cost – including both capex and opex expenditure – between the conventional truck haulage system and an in-the-pit (ITPS) solution. In some cases, the capital expendititure of the conventional haulage system may be initially lower, but the lower operation cost of the ITPS system will compensate the difference over the years to come. The key decision criteria are the length of the break-even period and the cumulative monetary savings at the end of the observation period.
In the long run, in-the-pit crushing is the ideal solution. Depending on the conditions, an in-pit crushing solution can achieve full or partial replacement of trucks for material transport in and out of a mine. The result is a more efficient production with both economic and environmental benefits.
Instead of feeding a dump truck, an excavator located on the muck pile loads material directly into the hopper of a Lokotrack® mobile crushing plant. Crushed rock is then transported to an in-pit belt conveyor via mobile Lokolink conveyors. The conveyor carries crushed rock from the Lokotrack to the fixed secondary plant for further processing – no dump trucks are needed. When blasting is performed, the Lokotrack and Lokolink conveyors move to a safe distance. After the blast, a wheel loader cleans the quarry floor and the Lokotrack plant moves to the new muck pile. Operation resumes with minimal production downtime.
Reduce costs and environmental load
Replacing the conventional truck fleet with a fully mobile primary crushing plant linked to mobile, shiftable and bridge conveying systems brings significant savings in production costs, as minimized energy is used to move the waste from the pit to the waste dump. It also reduces the load on the environment.
