    Abstract: The invention relates to fiberizing apparatus for forming mineral wool and a process using that apparatus. The apparatus comprises a set (1) of at least three rotors mounted for rotation about respective horizontal axes. Melt is poured onto the top rotor (4) and thrown onto subsequent rotors in turn (5, 6 and 7) with the result that fibres are thrown off. The rotors all rotate to give an acceleration field of at least 50 km/s.sup.2, and are spacially arranged in respect to one another so that a line drawn from the axis of the first rotor (4) to the axis of the second rotor (5) makes an angle (C) of 0-20.degree. below the horizontal.
