Abstract
The present invention furnishes a device for fiberizing molten mineral materials in order to produce mineral fiber products by means of a spinner (2) having a multiplicity of orifices (6; 8) provided in the peripheral wall (4) thereof, for centrifuging molten mineral materials (10; 12) supplied to the spinner (2), with the spinner (2) comprising on the inside (14) of the peripheral wall (4) compartments (18; 20) arranged in sections and delimited by baffles (16) for separately feeding and separately receiving a respective molten material (10; 12) to at least one associated orifice (6; 8), with the orifices (6; 8) extending at least approximately in a radial direction through the peripheral wall (4). In the present invention a method for producing this device is moreover proposed.
