Olympic Aggregates wheel and track-mounted technologies
Within the wide Karelian forests in northeastern Russia hide several high-quality aggregates deposits. Thanks to the constant quality, these valued rocks play a significant role in the construction of the infrastructure for the 2014 Winter Olympics in Sochi, Russia.
Benefiting from the nearby railway connection, several grades of aggregates are loaded into trains that travel the huge distance of over 2,000 kilometres to the Black Sea coast.
Until now, the company “Karelprirodresurs”, has crushed, screened and transported the aggregates from the Leppäsyrjä and Räikönkoski quarries for road projects near St. Petersburg and Moscow. The main consumer has been the road building specialist ZAO “VAD”. In the coming years, a significant amount of Karelian aggregates will be shipped by rail south to the Sochi area. Aggregates production in Karelia will increase to 25 million m3 per year as analysts expect, and a big part of the aggregates will travel south to the Sochi area to secure a solid base for the building operations for the Olympic Games.
Tracked and wheeled technologies combined
The Leppäsyrjä plant, which started up in August 2007, is benefiting from a combination of mobile, track and wheel mounted technologies, supplied by LIMING Minerals.
After blasting and hammering, the hard diabase is fed between the jaws of the Lokotrack LT125 primary plant.
A fleet of Volvo dump trucks take the crushed materials to the secondary plant, about one kilometre away. A massive feeder distributes the gravel into the wheel-mounted Nordberg NW550GP secondary plant, which has the large capacity GP550 cone
A wheeled NW2060CVB screen plant separates the required product cuts before the tertiary crushing stage. The four-decked inclined
screen has a large screening area on each deck to meet the capacity requirements
Cubicity created with a Barmac plant
The cubicity demands created by the new Olympic and road projects is met by a wheeled Nordberg NW 7150C tertiary Barmac plant.
Besides the crushers and screens, the LIMING Minerals delivery consisted of vibrating chutes, product conveyors, a magnetic separator and the complete plant design.
The second Karelprirodresurs plant at Räikönkoski has a similar wheelmounted process concept to that at Leppäsyrjä. Primary crushing is done with a Lokotrack LT125 mobile jaw plant, and the further processing with wheel-mounted units.
