| A method for making a mould used in the manufacture of foundry castings comprises (a) providing a water-insoluble particulate material, such as sand; (b) combining the particulate material with a binder, preferably containing polyphosphate chains and/or borate ions and water; (c) heating the mixture to a temperature in excess of 100 °C; (d) forming the mixture into a desired shape; and removing water from the mixture, with air, at a temperature in excess of 100 °C. The method ensures that the volatilisation of the water does not cool the mixture and, therefore, the production cycle is hastened and efficiency is improved. | ||||||

Gießereialtsand wird dadurch gereinigt, daß er in einem Bearbeitungsraum umgewälzt und auf die Altsandpartikel die Binderhülle aufbrechende und vom Sandkorn lösende Reibungskräfte zur Wirkung gebracht werden und das entstehende Stoffgemisch unter Anreicherung des Sandanteils physikalisch gereinigt wird. Um eine effektive Reinigung zu ermöglichen, wird ein Teil des Stoffgemischs nach Durchlaufen der Reibungszone aus dem Bearbeitungsraum in einen getrennten Reinigungsraum abgezogen und gereinigt und der vorgereinigte Altsand in den Bearbeitungsraum zurückgeführt. |

| Disclosed are an apparatus for and a method of reclaiming molding sand capable of increasing a recycling efficiency of used molding sand and of highly enhancing the purity of a reclaimed molding sand. By crushing a lump of molding sand segregated from a molding box, used molding sand can be formed. In order to remove coking agents sticking on a surface of the used molding sand, an impeller disposed in a rotatable grinding drum is rotated after charging the used molding sand into a casing in which the rotatable grinding drum is disposed. The coking agents sticking on the surface of the used molding sand are removed due to collision and a mutual frictional rolling contact between the used molding sand and the rotatable grinding drum with the aid of rotational force of the impeller after having accomplished charging the used molding sand toward the impeller. Fine powders of the coking agents segregated from the used molding sand are exhausted through a dust collecting port together with external air introduced into the casing through an inlet pipe of a rotational shaft disposed in operative association with a motor at the center of the casing. <IMAGE> | ||||||
