摘要： In an asphalt mixing plant, a portion of the heat used to vaporize water in the process of drying aggregate is recovered by conducting dryer exhaust gases through parallel ducts which extend serially through the aggregate cold feed bins. These parallel ducts are vertically elongated for optimum heat transfer and to avoid impeding aggregated flow. The ducts have vertically extending external fins for greater contact with the aggregate in the bins. They also have horizontally extending internal fins for improved heat transfer between the exhaust gases and the ducts. The ducts are peaked, and conforming protective caps are provided to prevent damage to the ducts during loading of the bins. Water injection is used to initiate condensation of water vapor in the exhaust gases.

摘要： In a continuous drum mix asphalt plant, dust is exhausted from an intermediate zone of the drum mixer between its drying and mixing zones. The dust is exhausted radially through openings into a collection housing, which communicates with a dust collector and exhaust blower. An end housing at the discharge end of the drum communicates with the same dust collector and blower. Dampers are provided to control the relative proportion of air exhausted from the drum through the respective housings. Aggregate deflectors on the interior wall of the drum at the intermediate zone allow air and dust to flow while inhibiting the flow of aggregate. The collection housing surrounding the intermediate zone is of a size such as to produce a reduction in the velocity of the air as it passes out of the drum. Consequently, it serves as a knock-out box for the collection of larger particles which are carried out of the drum, but which settle out of the air stream as a result of the velocity decrease. These collected particles are reintroduced into the drum by scoops on the exterior of the drum. These scoops are also used for the introduction of recycled asphaltic concrete.
摘要翻译：在连续的鼓式混合沥青设备中，粉尘从其在干燥和混合区域之间的鼓式混合器的中间区域排出。灰尘通过开口径向排放到收集壳体中，该收集壳体与集尘器和排风机连通。滚筒排出端的端部壳体与相同的集尘器和鼓风机连通。提供阻尼器以控制从鼓通过相应外壳排出的空气的相对比例。在中间区域的鼓的内壁上的聚集偏转器允许空气和灰尘流动同时抑制聚集体的流动。围绕中间区域的收集壳体具有的尺寸使得当空气流出滚筒时，空气的速度降低。因此，它用作收集较大的颗粒的敲除箱，其由滚筒进行，但由于速度的降低而沉淀在空气流中。这些收集的颗粒通过滚筒外部的勺子重新引入滚筒。这些勺子也用于引进再生沥青混凝土。
