摘要： The present invention furnishes a method for producing mineral wool wherein a molten mineral material is fed into a spinner (1) the peripheral wall (2) of which comprises a multiplicity of orifices with small diameters wherethrough the mineral molten material is centrifuged to form filaments which are subjected to a supplementary attenuating effect of a gas flow flowing along and heating the peripheral wall (2) of the spinner (1) and generated by a concentric annular burner (8) arranged concentrically to the spinner (1), and wherein the exit area of the burner (8) is subdivided into an annular radially inner hot zone and an annular radially outer cooling zone of substantially lower temperature; the invention moreover concerns an apparatus for implementing the method.
