Date Mar. 21, 1991.A method of destructing mineral-wool scrap and reusing the scrap in the manufacture of mineral wool includes introducing the mineral-wool scrap in a finally divided state into a container causing the finely-divided mineral-wool scrap to pass through a heating zone generated by an oxygen burner such as to convert the mineral-wool scrap to a liquid state and delivering the molten mineral-wool scrap into a furnace in which a melt for manufacturing mineral-wool is produced or to an intermediate container mounted between the furnace and a spinning machine. When the molten mineral-wool scrap is being delivered to the intermediate container, molten material taken from the furnace is also delivered to the intermediate container.</p> |
