TOWER STRUCTURE OF A PRE-HEATING TOWER OF A PLANT FOR THERMALLY PROCESSING MINERALS, AND METHOD FOR CONSTRUCTING THE PRE-HEATING TOWER

摘要

The present invention relates to a tower structure (12) of a pre-heating tower of a plant for thermally processing minerals, comprising a plurality of support beams (16), which extend vertically and mutually parallel and are interconnected by means of cross-supports (18-26), and a plurality of mounting positions each for the attachment of a platform (14) to the tower structure (12), wherein the cross-sectional profile of at least two of the support beams (16) changes over the height of the tower structure (12).
