Abstract (en)
[origin: US4668099A] A conical spiral mixer with a conically tapered mixer container, includes a mixing spiral that moves parallel to the conical inner wall of the mixing container, the lower end of the mixing spiral extending through an opening in the container bottom below which is a swingable and pivotable bearing. The sealing between the shaft of the mixing spiral and the opening in the container bottom, is provided by means of a spherical sealing body pivotably supported on the shaft of the mixing spiral, but at an angle to the axis of the mixing container. The sealing body takes part in the swing movement of the shaft of the mixing spiral, but not however in its pivoting or spinning movement.
