Abstract
A hollow mixing bar having at least one blade pivoted at one end by attachment to the mixing bar such that it is designed to rest against the mixing bar until the mixing bar is rotated. As the mixing bar is rotated the unattached end of each blade moves away from the plane of the mixing bar thereby contributing to the blending or decompaction action of the mixing bar. The blade can also protect apertures in the mixing bar used for introduction of fluid materials through the mixing bar and the outlet apertures. The design of the mixing bar is especially advantageous in that it minimizes the initial torque necessary to blend or decompact solids and is readily removable for cleaning. In the preferred embodiment the mixing bar provides a wide range of blending action ranging from gentle vibration to violent agitation.
