The Sunsky Karier site can be considered a unique production facility which incorporates the latest engineering innovations.
Among others, the site being developed fully meets the requirements for industrial and environmental safety effective in Russia. The flexibility of the crushed stone production process parameters as well as the reliability and ease of operations are the distinctive features of the site.
The unit has also an effective logistic system – the site is located in proximity to Petrozavodsk and Kondopoga cities, to a railway station and to a federal highway.
This makes the product supply smooth to users all over European Russia. The site is also located near the Metso service centre in Petrozavodsk city – specialists at the centre provide technical support for the project by responding to any questions the customer might have.

1. The primary stage is represented by Metso’s Nordberg C145 stationary jaw crusher. The primary product is supplied to a storage site by a conveyor and transported for further processing.
2. The secondary stage uses a Nordberg HP500 cone crusher which feeds a Metso TS 5.3 screen, producing high-quality crushed stone of 25–60 mm or 40–70 mm grades.
3. The third stage includes a Nordberg HP4 cone crusher and a Metso TS 3.3 screen producing 20–40 mm grades.
4. The fourth stage uses a Barmac 9100 VSI crusher and a TS 3.3 screen to produce fine cube-shaped 5–20 mm grades.
