Treating foundry mold material containing core sand and binder, to regenerate the sand for reuse, by subdividing the sand while still hot into stream for wet regeneration and stream for use as drying heat source
Treating foundry mold material containing core sand and binder, to regenerate the sand for reuse, by subdividing the sand while still hot into stream for wet regeneration and stream for use as drying heat source
Treatment of foundry mold materials, containing core sand and binder involves subjecting the core sand (Sk) bonded with inorganic binder(s), while still hot after casting, to dry separation (A1) from the casting (M1), dry crushing (B1) and subdivision (E1) into two hot partial streams (T1, T2).
