Abstract:
A process for manufacturing mineral fibers, comprising the steps of:simultaneously feeding molten mineral to be fiberized to rotating peripheral surfaces of first centrifuging wheels of at least two fiberizing machines placed side by side in a chamber having walls, to accelerate the molten material; conveying the material in a cascading fashion from the first centrifuging wheel of each of said at least two fiberizing machines to at least one further oppositely rotating centrifuging wheel of each of said at least two fiberizing machines so as to convert the material into fibers by centrifugal force; and using a gas stream generated by the at least two fiberizing machines to pick up the fibers and to collect the fibers in a gathering device, wherein rotational axes of the centrifuging wheels of each of said at least two fiberizing machines are substantially parallel, and wherein the rotational axes of the centrifuging wheels of a first of said at least two fiberizing machines are set at a non-zero angle with respect to the rotational axes of the centrifuging wheels of a second of said at least two fiberizing machines, said non-zero angle being selected such that the gas streams generated by said fiberizing machines meet and combine.
