Mixer for conditioning core molding materials. Molding materials for the core room are predominantly made of new sand, (quartz sand or special sand) by mixing it with required binders.
Coresand mixers dispose of shovel-like mixing tools, they are used for batches and fed with binders and sand accordingly. Fig. 1 and 2 show execution examples of coresand mixers (KLEIN Anlagenbau AG). In special cases, the mixing process can also be performed immediately in the coremolding machine, e.g. with the continuous mixer (see cold-setting process).
