Abstract
A method for fiberizing mineral material with organic material includes centrifuging mineral fibers from molten mineral material with a first rotating spinner, changing the direction of the mineral fibers to form a downwardly moving veil of mineral fibers, establishing a flow of molten organic material moving toward a second rotating spinner positioned within the veil, dividing the flow of molten organic material into a plurality of streams, directing, by means of conduits, individual ones of the plurality of streams toward the peripheral wall of the second rotating spinner, the conduits shielding the molten organic material from heat from the first rotating spinner, and centrifuging organic fibers from the molten organic material.
