ABSTRACT:
A combination clay mixing and extruding apparatus for mixing dry powders and water to form a moist clay which can alternately be held in the mixing chamber, or, as desired, can be automatically extruded into cylindrically shaped logs. Due to the unique design of the apparatus, the extrusion operation is commenced by merely reversing the direction of rotation of the drive means of the device. For more compactness, the unit embodies in-line mixing and extrusion chambers. A unitary shaft drives both the mixing blades of the mixing chamber and the extruding auger of the extrusion chamber. The shaft is cantilevered within the chambers and is journaled in bearings located exteriorly of the chambers so as to protect them from the abrasive and corrosive effects of the powder and water.
