Abstract
It would be very advantageous if the condition of molding materials (sand-binder systems) in regen-erator units used in foundries could be monitored in real-time. This work presents the results of inves-tigations in this direction. It is shown that the condition monitoring can possibly be based on imped-ance spectroscopy because the resulting curves are characteristic of the material used. New and used sands as well as two-component mixtures of sands and binders showed a systematic behavior, which allows the sand or the composition of the mixture to be identified (classified) in the future.
