VERFAHREN ZUM ABSONDERN VON FASERN AUS ZUSAMMENGESETZTEN MATERIALIEN.
摘要
<p>A resin reinforced fibre product such as glass fibre impregnated with a thermosetting resin is treated to recover fibre by initially shredding the waste, pulverizing the shredded waste and sieving the pulverized waste to separate the free fibres. The remaining waste is milled to produce a fine powder suitable as a filler. The pulverizing is completed without classification and a portion of the pulverized product above a nominal cut size recampaigned. Free fibres are separated by an airlift during the sieving process.</p>
