摘要 |
The invention relates to the technology of manufacturing mineral fibres, glass wool or rock wool and, more specifically, to the recycling of scrap in the manufacturing plants. The scrap, reduced to fragments, is introduced into the delivery channel through which the molten glassy material passes before reaching the fiberizing machine. The device of the invention includes a pressure-isolating feed system. Large quantities of scrap may be introduced without disturbing the manufacture of the mineral wool. |
