Pneumatic moulding sand reclamation in the linear regenerator system

This article covers the analysis of the pneumatic moulding sand reclamation, made of different types of binders. The research has been carried out for the sand with resin binder (phenolic - formaldehyde and furan resins) as well as water glass (hardened with flodur and arconite hardener). Reclamation has been carried in the pneumatic conveying system in the linear regenerator in the technical scale. Evaluation of the effectiveness of the reclamation has been made on the basis of tests determining the contents of binder's components before and after the process and on the basis of the sieve analysis.
