Date Jun. 12, 1997A process is provided for making filled mineral fiber products which comprises applying mineral melt to a rotating fiberizing rotor and thereby throwing from the rotor as fibers and forming a substantially annular cloud of fibers, spraying binder into the annular cloud of fibers, carrying the fibers axially from the rotor towards a collector surface and collecting the fibers on the collector surface as a web. The process includes spraying into the substantially annular cloud a slurry which has specific gravity of at least 1.1, preferably at least 1.2, and which comprises a substantially stable liquid dispersion of particulate material in an aqueous binder. |
