CA 2202208
The present invention proposes a method for producing mineral wool products by using a spinner (202), through the orifices (206 and 208) of which at least two supplied molten mineral materials (210 and 212) are centrifuged, with each one of said two molten mineral materials being centrifuged at least partly through orifices (206 and 208) which are separate and assigned to a respective one of the two molten materials in order to produce pure fibers (220 and 222) from the molten materials. The present invention furthermore furnishes a device for centrifuging molten materials (210 and 212) for producing mineral fiber products by means of a spinner (202) having a multiplicity of orifices (206 and 208) provided in its peripheral wall (204) for centrifuging molten materials (210 and 212) supplied to the spinner (202), with the spinner (202) comprising on the inside (214) of its peripheral wall (204) compartments (216 and 218) arranged in sections for separately supplying - or separately receiving, respectively - a respective one of the two molten materials to at least one associated orifice.
La présente invention consiste en un procédé de fabrication de produits en laine minérale faisant appel à un centrifugeur (202) dans les orifices (206, 208) duquel sont introduites au moins deux matières minérales fondues (210, 212) qui sont centrifugées, chacune desdites matières étant centrifugée au moins partiellement par des orifices (206, 208) distincts correspondant à chacune des deux matières fondues, pour produire des fibres pures (220, 222) à partir des matières fondues. La présente invention a également trait à un appareil servant à centrifuger des matières fondues (210, 212) pour produire des produits en fibres minérales en utilisant un centrifugeur (202) à orifices multiples (206, 208) répartis sur sa paroi périphérique (204), de manière à centrifuger des matières fondues (210, 212) dont est alimenté le centrifugeur (202), ledit centrifugeur (202) comportant à l'intérieur (214) de sa paroi périphérique (204) des compartiments (216, 218) fournissant ou recevant respectivement l'une des deux matières fondues par au moins un orifice correspondant.
