Systems and processes for recycling glass fiber waste material into glass fiber product

摘要

Systems and processes of the present invention for recycling glass fiber waste into glass fiber product include a supply of scrap glass fibers having a mean average length of less than about 5 millimeters; a crusher having at least one pair of rotatable rollers which rotate at essentially the same speed, the rollers having intermeshing protuberances for crushing scrap glass fibers passing therebetween; and an air separating device for separating a first portion of crushed glass fibers having a mean average length of less than about 3 millimeters from a second portion of oversize glass fibers.
