Abstract

PURPOSE: To improve the removal ratio of shots and recovery of inorganic fibers, by lifting inorganic fibers containing shots in a vertical hollow duct by a carrying gas stream at a specific speed.
CONSTITUTION: A molten inorganic material is extruded through the spinning furnace 1 into the filaments 2, formed into fibers by an exhaust gas of the jet burner 3, etc., and transported by the high-speed air stream, then introduced into the vertical hollow duct 5 which changes the flow of the air into a rising current. The rising speed of the air current is maintained at 0.2W0.6m/sec in the duct 5, and only shots contained in the inorganic fibers drop by the difference in bulk specific qravity, and are collected at the bottom of the duct 5. Inorganic fibers free of the shots rise in the duct 5 and recovered by the recovery device 6.
