The increasing use of offshore wind power around the world has shown a growing need for heavy weight to ballast the renewable energy turbines. LKAB Minerals supplies high density MagnaDense to offshore wind projects, either as loose ballast or mixed into concrete. Our MagnaDense, manufactured from the mineral Magnetite, reaches densities up to 5.2 t/m3.
Wind mill foundations stay put with heavy weight aggregate
When constructed, the wind turbines require secure foundations that are unaffected by undersea currents and lifetime abrasion. By nature these foundations need to have a considerable weight in order to withstand the motions of the sea and the stresses imposed by the rotating blades.
