Abstract

En fibreringsrotor i en maskin for fremstilling av mineralfibre ved fri sentrifugering omfattende en felg (12) til utsiden av hvilken det smeltede materialet som skal fibreres til fibre mates fra en fordelingsrotor eller en annen fibreringsrotor. Rotoren omfatter en indre væskekrets med væskeutslippsåpninger (8,10) på felgen (12), hvilke åpninger befinner seg i den felgdel der materialet avsettes. Dette arrangement med avkjølingsåpninger (8,10) muliggjør at temperaturen i bæreren kan reduseres i de varmeste områder mens de tilsvarende temperaturgradienter reduseres. Når temperatur-gradientene reduseres på felgen av de sentrifugerende rotorer under det smeltede materialet som fibreres, blir produksjonsbetingelsene og derved produkt- kvaliteten (fiberlengde og forsinkelsen i tapet av kvalitet på grunn av rotor-slittasje), betingelses-stabilitet (blandinger særlig med snevert arbeidsområde) eller slittasjen av utstyret, vesentlig forbedret.A fibrating rotor in a machine for producing mineral fibers by free spin comprising a rim (12) to the outside of which the molten material to be fibrated to fibers is fed from a distribution rotor or other fibrating rotor. The rotor comprises an inner liquid circuit with liquid discharge openings (8, 10) on the rim (12), which openings are in the rim part where the material is deposited. This arrangement with cooling openings (8,10) allows the temperature of the carrier to be reduced in the hottest areas while reducing the corresponding temperature gradients. When the temperature gradients are reduced on the rim of the centrifugal rotors under the molten material being fiberized, the conditions of production and thus the product quality (fiber length and the delay in loss of quality due to rotor wear) become condition stability (mixtures especially with narrow working range). ) or the wear of the equipment, significantly improved.
