Reclamation of spent moulding sands with inorganic binders in the vibratory reclaimer REGMAS

Abstract

The results of the reclamation of spent moulding sands with inorganic binder in the prototype vibratory reclaimer REGMAS - are presented in the paper. Spent moulding sands with modified water-glass, burned as well as not burned, present in a form of agglomerates (lumps), were subjected to the reclamation processes. During individual reclamation cycles the reclaimer efficiency and vibrations amplitudes were determined and physicalchemical and strength investigations were performed for the obtained reclaim materials. The obtained reclaim was used as a component of the matrix of moulding sands with water-glass in the Floster S technology, in which the reclaim constituted 100%, 80% and 50% of the sand matrix - respectively.
