Abstract (en)
[origin: WO0070147A1] A method and system provide for the production of mineral fiber boards using at least 25 % (preferably at least about 90 %) inorganic fibers having enhanced uniformity, compressive strength, and dimensional stability. The source of fibers may be pre and/or post consumer recycled fiberglass. A liquid slurry of solids, including at least 25 % inorganic fibers having an average length of at least about one-half inch, with a solids consistency of about 0.4-8 % is formed. A pack at least about one inch thick is formed from the slurry using a foraminous element, and water is extracted. The pack is dried, and binder may be added and cured, to produce a product at least about one inch thick. Exhaust gases from the drier may be filtered by passage through the pack prior to drying, while also facilitating dewatering of the pack.
