摘要： An apparatus for preheating particulate material in which the particulate material is transferred from one or more upper storage bins to a circular lower chamber that has an outer, essentially annular, portion which serves as a gas flow passage. The particulate material is directed from the feed bin or bins into a plurality of essentially vertical cylindrical feed cassettes via intermediate feed ducts. The lower chamber has a flat roof which is in contact with the bottom portion of the vertical feed cassettes. The vertical feed cassettes are approximately evenly spaced on top of the outer perimeter of the flat roof. The particulate material is preheated in the annular flow passage by hot kiln gases flowing in countercurrent heat exchange relationship with the particulate material. Each feed cassette is completely segregated from its adjacent cassettes, and the bottom of each cassette is positioned over a hole in the flat roof of the lower chamber to thereby enable the particulate material to fall from each cassette into the annular flow passage section of the lower chamber. A plurality of particulate discharge mechanisms, the number of which correspond to the number of cassettes, discharges particulate material that has fallen into the annular flow chamber from the overhanging cassettes into a material outlet located in the floor located at the center of the lower chamber.
摘要翻译： 一种用于预热颗粒材料的装置，其中颗粒材料从一个或多个上部存储箱转移到具有用作气体流动通道的外部，基本上环形的部分的圆形下部室。 颗粒材料通过中间进料管从进料仓或料仓导入多个基本垂直的圆柱形进料盒。 下室具有与垂直进料盒的底部接触的平坦屋顶。 垂直进料盒在平坦屋顶的外周的顶部上大致均匀地间隔开。 颗粒材料在环形流道中通过与颗粒材料逆流热交换关系流动的热窑气体预热。 每个进料盒与其相邻的盒完全隔离，并且每个盒的底部定位在下室的平屋顶中的孔上方，从而使颗粒材料能够从每个盒落入下部的环形流动通道部分 房间。 多个颗粒排放机构（其数量对应于盒的数量）将从悬垂盒中掉入环形流动室的颗粒材料排放到位于位于下室的中心的地板中的材料出口中。
