Fremgangsmåte og innretning for fremstilling av mineralull ved indre sentrifugering

摘要

The invention concerns a device for forming mineral fibres by internal centrifugation comprising a centrifuge (1) capable of rotating about an axis X1, in particular vertical and whereof the peripheral wall (2) is perforated with a plurality of orifices, high-temperature gaseous drawing means in the form of an annular burner (9), pneumatic means for controlling/adjusting the dimensions of the fibres in the form of a blow ring (10). The control and adjusting of the dimensions carried out by said pneumatic means are completed by another means, including a mechanical means comprising a cooled plate (12) arranged around the centrifuge (1) opposite its peripheral wall (2) at least. The invention also concerns a method using said device and its uses.
