Every hour, the belt moves 8,700 t of ore out of the mine and down to the processing plant, which is located at an altitude of 1,600 m. this massive volume of ore is large enough to fill some 200 heavy-duty trucks. without the conveyor belt, there would be no mine, says operations director ricardo funes maggi, of mine operator minera los.For conveyor belts up to type ep /4 under low stress in temperature climates. y 20 400 150 for conveyor belts from type ep500/3 under high stress in temperature climates. x 25 450 120 for conveyor belts from type ep 500/3 under high stress in arid, humid and alternate climates. w 18 400 90 for conveyor belts from ep 500/3.
May 13, the aim of the study was to create a complex simulation model of the belt conveyor-based transport system of an actual polish copper mine. the model was parameterized with the mined orebody data (lithology and quality), mining schedules, the operational time of vehicles supplying the ore from mining fields, the velocities of the system’s parts, and discretized flow times of ore batches and.Operations at chuquicamata copper mine in chile. commissioning was completed in four months. abb has provided engineering design, gearless conveyor drives, electrical equipment for power supply, energy distribution and automation of a new underground and overland conveyor system at the world’s largest open pit copper.
