ABSTRACT:
Apparatus useful for the malaxation of a charge such as foundry sand, a ractory or abrasive particulate-like solid, powdered marble, gravel or like building materials embodying two mixing zones to first form a pre-mix of the charge and a constituent of a binder-hardener system and then form an intimate and homogeneous mixture of the pre-mix and the other constituent of the system within a few seconds followed by immediate evacuation or emptying of the resultant mixture. At least the second mixing zone is a mixing vessel with a cylindrical or conically tapered inner wall inside of which is rotated a drive shaft with radial arms, each bearing a hammer on its outer end, the hammers orbiting in the vessel with a clearance of only a few millimeters with the inner wall to attain thin film malaxation.
