Metso has supplied the world's largest mobile crushing plant to the Altay Polimetally LLP copper mine in Kazakhstan.
According to the company the Lokotrack LT200 giant jaw plant will cut costs by decreasing dump truck traffic at the open pit mine.
Included in the delivery of the crusher are mobile feeding and conveying systems to move the crushed ore, as well as installation of the systems and training.
The total value of the work is more than €11 million.
"Today, open pit mines are studying globally the possibility to save costs and environment at primary crushing and conveying stages by decreasing on-site ore trucking.
"With this kind of large scale, fully mobile equipment, we can well meet this customer demand,” Metso's in-pit crushing solutions business manager Jorma Kempas said.
The case for increased in pit-pit crushing and conveying (IPCC) was recently pushed by SRK Consulting's Scott McEwing.
"While an IPCC requires an investment, in the long-term it helps mining companies reduce their capital and operating costs," he explained.
"Your traditional truck and shovel mining operation is equipment intensive and has a heavy reliance on diesel fuel.
"You have loaded trucks travelling up and out of the mine 24 hours a day, so you need a fleet of trucks and a roster of drivers. You're burning up huge amounts of diesel and wearing tyres, at a time when there is a worldwide shortage of them," McEwing stated.
"The IPCC option provides a significant saving in operating costs because you are using less trucks, less fuel and less manpower. And to me there's no doubt that reducing carbon emissions is also becoming a key driver to having an IPCC."
According to Metso, its Lokotrack LT200 weighs almost 400 US tons and has a capacity of 2500 tons of ore per hour.
The complete IPCC system weighs more than 800 tons, and is electric driven and withstand operational temperatures ranging from more than 35 degrees Celsius down to minus 35 degrees.
At Kazakh mine the blasted copper ore is fed using a mobile apron feeder to the jaw plant, and then conveyed using Nordberg LL16 mobile conveying system, and track-mounted stacker to the mine’s conveyor network.
The loading height of the tracked mobile apron feeder is six meters, and it has a feed hopper volume of 24 cubic meters.
The LT200 jaw plant, equipped with Metso’s biggest C200 jaw crusher, can crush ore feed lumps up to 1.2 meters in size.
