摘　　要：根据树脂砂生产线型砂输送特性及工艺，选择合适的物料流动形态及气力输送装置，使输送系统达到密相流态气力输送的效果，适应较长距离、增加输送量的工艺要求。According to the properties and process of sand transportation for resin sand production line, the proper flow pattern and air-transporting system were selected. The liquid state of extensive air transportation for system can meet the process requirements of long distance and high transporting volume.
