DEVICE FOR PRODUCING EXPANDED GRANULAR MATERIAL
To provide a device for producing an expanded granular material, capable of expanding a raw sand having a fine grain size and a narrow grain band.SOLUTION: The present invention relates to a device including a furnace 3 having a furnace shaft 4 including an upper end 5 and a lower end 6, for producing an expanded granular material 2 from a granular sand mineral material 1 using an expanding agent. A conveying path 7 passing through a plurality of heating zones 8 arranged separated from each other in a conveying direction 12 extends between two ends. At least one feeding means 10 is provided at one of the two ends, for charging at least unexpanded material into the furnace shaft in a direction of one of the two ends. At least one guide element 13 is provided which is disposed in the furnace shaft, the guide element forming a gap 15 with an inner wall 14 of the furnace shaft, at least in a region at one end of the two ends. The at least one feeding means is set to charge material into the gap.SELECTED DRAWING: Figure 1
【課題】細かい粒サイズと狭い粒子帯域とを有する原砂の膨張を可能にする、膨張した粒状物を製造するための装置を提供する。【解決手段】上端５及び下端６を含む炉シャフト４を有する炉３を備える、膨張剤を用いて砂粒状鉱物材料１から膨張した粒状物２を製造するための装置であって、搬送方向１２に互いに分離されて配置された複数の加熱ゾーン８を通る搬送経路７が２つの端の間に延び、さらに、２つの端のうちの一端において、少なくとも未膨張材料を、２つの端のうちの一端の方向で炉シャフトに装入するために、少なくとも１つの供給手段１０が設けられており、炉シャフト内に配置された少なくとも１つのガイド要素１３が設けられ、ガイド要素は、少なくとも、２つの端のうちの一端の領域において、炉シャフトの内壁１４と隙間１５を形成し、少なくとも１つの供給手段が、隙間に材料を装入するように設定されている。【選択図】図１
