ABSTRACT:
A final mixing chamber for mixing together previously separately prepared mixtures of foundry sand/binder and foundry sand/catalyst which are delivered to the upper end of the final mixing chamber having a discharge aperture in its lower end and a vertical rotatable shaft extending centrally through the chamber with blades fixed thereto. Some of the blades extend radially from the shaft and are made up of mixer blades which direct material downwardly and deflector blades which deflect material upwardly, while the remaining blades are scraper blades which are attached between adjacent ones of the other blades at their extremities so as to scrape the internal surface of the chamber.
