Abstract
Apparatus for producing mineral fibers comprises a spinner mounted for rotation to centrifuge mineral fibers from molten mineral material, an annular blower positioned concentrically outwardly from the spinner for turning the mineral fibers downwardly and inducing a downward flow of air around the spinner, and an airfoil mounted above the blower to provide a downwardly converging annular passageway above the blower for the induced air, the blower and the airfoil forming a substantially continuous curved surface, being curved radially inwardly at the blower.
