| 摘要 | A method of reclaiming casting sand comprises the steps of throwing casting sand into a processing tank (1) and reclaiming the casting sand while air pressure in the processing tank (1) is kept lower than air pressure outside the processing tank, and discharging the reclaimed casting sand from the processing tank while the internal air pressure is kept higher than the external air pressure. An apparatus for reclaiming and cooling casting sand, comprising means (p) for fluidizing casting sand, means disposed above the fluidizing means for cooling the fluidized casting sand, means disposed above the cooling means for scaling (2) bonds from particles of the casting sand by friction, and means disposed above the cooling means for having relatively large dust particles sedimented is characterized by the bond-scaling means, being configured such that the reclaimed casting sand can be discharged into the fluidizing means therethrough. | ||||||
