Abstract of the Disclosure A device for cooling castings and for treating moulding sand comprises a driven, rotatably journalled drum provided with internal catches extending sub- stantially axially between an inlet end and an outlet end of the drum. For improving the stirring effect of the catches and for avoiding damage of castings and loss of valuable dust from the moulding sand, the catches have a stronger scooping effect near the inlet end than near the outlet end.
