Abstract

Apparatus for making molding sand has one or more housings defining upright cylindrical chambers and being movable with reference to a plate-like support to and from positions of register with an aperture in the support. Each chamber is normally closed at its upper end by a closure which has outlets for sand and one or more binder materials (such as clayey matter, pulverulent iron oxide, pulverized wood and/or others), and a rotary propeller is movable axially in each chamber to mix the ingredients in the circumferential direction as well as axially of the respective chamber.
