Abstract
Abstract A transportable rotary mixer for pig-iron. A container has a shaft at each end, rotatably journaled in a rocker bearing mounted on a base supported on a movable carriage. At least one shaft has a driven gear wheel secured about it and a platform surrounding its base and resting on the outer surface thereof. The shaft has a central bore, out of which a pin axially extends, being journaled against rotation therewith but to accompany the pivotal movement thereof. Means are provided which fixedly connect the pin to the platform for joint movement. The platform mounts driving means for the driven gear.
