1 The Norwegian producer NorStone
NorStone is Norway’s largest producer of gravel products. The company supplies aggregates for concrete and asphalt, stone cladding for coastal regions, and other special products. Each year, NorStone’s production facilities produce over 6.6 million tons of gravel products of various sorts and qualities. The demand is large, and even with its present annual production capacity of 2.3 million tons of material the Tau plant can scarcely meet the demand. It is therefore all the more important to ensure high availability of the plant and minimize unplanned downtime.
