Claims (4)

OBJECT OF THE INVENTION 1. A process for recovering glass melting raw materials from waste generated during spinning of a continuous glass fiber, wherein the spinning waste is pre-comminuted, is heat treated in the temperature range below the softening temperature of the continuous glass fiber and above the temperature of the deposited organic and / or the inorganic ingredients are comminuted by the topop, characterized in that the pre-shredding waste is pre-comminuted mechanically under the nozzle dispenser to be subjected to a stepwise thermal comminution in a predetermined loading height while being heated to a temperature in the first stage of processing between 450 and 830 ° C and the deposited organic and / or inorganic constituents are combusted and then cooled down to 150 ° C for a short time, collapsed brittle, and the material thus obtained is semi-mechanically comminuted into a flowing glass powder of the size grain size 3 mm. 2. A method according to claim 1, characterized in that the winding process is interrupted, followed by mechanical pre-comminution of the glass strand after the yarn tension. 3. Method according to claim 1, characterized in that the height of the batch of pre-comminuted wastes during the thermal comminution is up to 360 mm, in the case of the application of the temperature from all sides predominantly = 360 mm and in the case of heat from one side is predominantly = 180 mm. 260954 · - 7 - 4. Process according to claim 1, characterized in that, during thermal comminution, the duration of the combustion at a temperature interval of 450 to 830 DEG C. is up to 2.5 hours and the duration of the burn time is 1 150 DEG to 0 DEG. 260954
