Outokumpu selected PMC Hydraulics as the supplier for its hydraulic and lubrication units in connection with the F3 project ongoing at the Kemi chrome mine. The renovation of the Kemi mine located in Southwestern Lapland was completed in autumn 2012. The mine was completely upgraded to meet the current demands. Owing to an increase in the demand for ferrochrome, the mining volumes of metallic ore have recently doubled.
In terms of hydraulics, the project went on stream during summer 2011, beginning with competitive bidding, in which PMC Hydraulics won the contract. The bidding was organized, because the value and scope of the project was significant. The criteria favoring PMC included its ability to provide a complete turnkey solution. The company was able to offer the entire package from installations to commissioning. – PMC’s offer was many-sided, including components, installation and the necessary know-how needed. The schedules held true throughout the project and the new lubrication units have been in test use since September, says Katri Hast, Maintenance Technician of the Kemi mine.
PMC Hydraulics supplied the Kemi mine with a hydraulic power pack equipped with a 1,500-litre tank. The company also provided lubrication units with capacities of 1,500 and 1,000 litres respectively. The lubrication unit provides lubrication for the two cone crushers of the concentrator plant during the beginning of the process above-ground. The hydraulics unit then integrates all hydraulics used in the crushing plant machinery. Before this, every piece of equipment had its own unit. The Kemi chrome deposit is located near the city of Kemi on the Gulf of Bothnia. The deposit was found in 1959 and a few years after that, a decision to utilize the chrome was made. The mine and its concentrator plant were established in 1968. The ore from the mine is further processed at the near-by Tornio ferrochrome mill. PMC has previously collaborated with Outokumpu’s Tornio Works unit, but the agreement with the Kemi mine is first of its kind. The Tornio Works uses the ferrochrome to manufacture stainless steel.
