Efficiency of mobile crushing station used in open-pit iron ore mining

Open-pit iron ore mines face increasing pressure to reduce haulage costs and carbon emissions. The efficiency of mobile crushing station used in open-pit iron ore mining has proven to be a game-changer, as it allows crushing to occur directly at the working face, eliminating long-distance truck hauls. OCP Machinery offers track-mounted and tire-mounted mobile crushing stations that combine a vibrating feeder, jaw crusher or gyratory crusher, and a discharge conveyor. By moving the crusher closer to the shovel, haulage distance can be reduced from several kilometers to just 200-300 meters, cutting diesel consumption by 40-60%. OCP’s mobile stations are designed for rapid relocation – a full set can be moved in 4-6 hours using two crawler transporters. The efficiency of mobile crushing station used in open-pit iron ore mining also depends on matching the crusher capacity to the shovel’s dipper size. OCP engineers calculate the optimal feed opening and conveyor speed to ensure continuous operation without bottlenecking.

In actual operation, a hydraulic excavator or wheel loader dumps run-of-mine iron ore (up to 1300mm) directly into the mobile station’s hopper. A heavy-duty vibrating grizzly feeder removes fines below 100mm, which bypass the crusher to reduce wear. The primary crusher (OCP’s JC series jaw crusher or HPY series gyratory) reduces ore to <200mm, and the product is discharged onto a foldable belt conveyor that can be extended to feed a stationary secondary crushing plant or a stockpile. For a Brazilian iron ore mine with 2,000 t/h requirement, OCP supplied a fully mobile crawler station with a JC140 jaw crusher (1400×1200mm feed opening) and a 1.8m-wide discharge conveyor. The measured efficiency of mobile crushing station used in open-pit iron ore mining showed a 52% reduction in haulage costs and a 35% decrease in total mining cost per ton. OCP’s custom capability allows us to add a magnetic separator for recovering high-grade lumps, and an optional dust suppression system using mist sprayers. Our direct factory pricing makes mobile stations 25% more affordable than comparable European brands, and we offer lease-to-own programs.

Environmental benefits are substantial: reduced truck traffic lowers dust, noise, and carbon footprint by an estimated 1,200 tons of CO2 per year per station. OCP’s 40 years of experience ensures robust design with high-pressure hoses and centralized greasing points. For an iron ore mine in Western Australia, OCP provided a semi-mobile station that achieved 95% availability over 8,000 operating hours. The efficiency of mobile crushing station used in open-pit iron ore mining can be further enhanced with OCP’s optional telemetry system for remote monitoring of crusher load, oil temperature, and wear life.
