Metso will a giant fully mobile, track-mounted crushing plant to Altay Polimetally copper mine in Kazakhstan. The contract also includes large mobile feeding and conveying systems to move the crushed copper ore for further processing, and installation supervision and training.
The giant mobile jaw plant, which, according to Metsok, will be the world's biggest fully mobile track-mounted Crushing plant, will be used at primary crushing stage at Altay Polimetally’s new open pit mine, situated in the Karagandy region. The equipment to Kazakhstan will be delivered within the last quarter of 2013.
The almost 400 tonne weighing Lokotrack LT200 – biggest ever built – is the key part of the system. The unit processes copper ore with a nominal capacity of 2500 tonnes per hour. The complete mobile system weighs over 800 tonnes, though can be moved easily along the mine face.
To withstand the harsh climate conditions during the winter, the whole mobile system is electric driven. The operational temperatures at the mine site vary from +35 to -35 °C.
At the new open pit mine, the blasted copper ore is fed using Metso’s MAF210 mobile apron feeder to jaw plant, and then conveyed using Nordberg mobile conveying system, and track-mounted stacker to the mine’s conveyor network.
The loading height of the tracked mobile apron feeder is 6 meters, and it has a feed hopper volume of 24 cubic metres. The jaw plant, equipped with Metso’s biggest C200 jaw crusher, can crush ore feed lumps up to 1,2 metres in size.
The wheel-mounted LL16 mobile conveyor has two conveyor elements, each 42 meter long. The track-mounted stacker has a discharge height between 3 to 10 metres.
Altay Polimetally LLP, based in Almaty, Kazakhstan, will extract at the new mine copper ore including gold. The planned ore extraction will be 3 million tons per year, and including host rock 10 million tons.
