ABSTRACT:
Salvaged foundry sand is reclaimed by introducing salvaged sand into a vacuum kneading tank, adding water and binder to the salvaged sand and kneading the salvaged sand under vacuum. A target strength value of the reclaimed sand is set and the amount of water and binder to be added to the salvaged sand on the basis of the temperature of the salvaged sand before kneading in the vacuum kneading tank so that reclaimed sand of the target strength value is obtained.
