ABSTRACT:
A method and an apparatus for fibring mineral wool by free centrifugation. An auxiliary gas current is generated at a distance from the centrifuging wheels in substantially the same direction as a main gas current which is emitted in the immediate proximity of the centrifuging wheels. This auxiliary gas current is obtained by passing air between the centrifuging wheels and/or through use of a supplementary blower ring. The invention applies particularly to the production of rock wool.
