Metso’s fully automated new crushing and screening solution will enable Franzefoss Steinskogen quarry in Norway to manufacture customised products with flexible production and reliable performance
Aggregates producer Franzefoss is upgrading capacity on its existing Steinskogen quarry site outside of Oslo, the Norwegian capital, to meet its long-term growth targets, and the company says
The new crushing and screening installation includes the design, fabrication, installation and commissioning for secondary and tertiary aggregate production.
In addition to the fully automated crusher and screening installation to monitor and ease the control of the operation, the new plant will be equipped with an automated truck loading station.
Full production is scheduled for March 2015.
The new secondary crushing plant system is targeted at 375tonnes/hour and will include one HP 400 cone crusher and two TS5.2 screens to produce railway ballast and end products of 4/16mm and 16/32mm basalt aggregate.
The tertiary stage, which relies on two HP 4 cone crushers and two TS 4.2 screens, will produce several fractions destined for concrete and asphalt use.
Conveyors and all ancillaries will ensure the handling and the storage of the material. The order has been included in Metso Mining and Construction’s Q4 2013 orders received.
“In-depth analysis of the customer’s needs, close collaboration with Franzefoss to position the tailor-made installation and confidence in Metso’s crushing and screening solutions paved the way to this new order,” says Eirik Brekke, vice president, Scandinavia sales area, Mining and Construction, Metso.
Franzefoss Pukk is a major aggregate producer in Norway with an annual production of 4 million tonnes through 12 different sites.
“Franzefoss builds its business on geological resources that are not renewable. Our utilisation and management of these resources poses special challenges and responsibilities,” says the company.
“Sand and gravel are severely limited resources, often with great environmental value. Our task is to identify the appropriate instances and secure resource base in the long-term. The deposits will be exploited in an environmentally sound manner.
“An intervention in nature satisfies the requirement of sustainable development only when it is recovered for reuse. The area can be restored to its original use as a natural area by planting or as a rural zone. Near the urban area it can be used for construction of residential and commercial, landfill or by infilling.”
In Norway, the use of crushed stone and gravel is about 9tonnes per capita/year, a total of about 50 million tonnes/year.
Franzefoss points out that covering 15km has meant the use of some 500,000tonnes of crushed stone, gravel and sand.
