ABSTRACT:
The conical screw mixer has a mixing vessel tapering toward the bottom region; in it, parallel to the inner wall, a rotationally driven mixing screw runs in the product chamber. At the bottom area a non-rotational compensating coupling is arranged, which is provided outside the product chamber and below the mixing vessel.
The seal between the rotating part of the angularly movable coupling and the product chamber is below the mixing vessel.
The seal between the rotating part of the angularly movable coupling and the product chamber is effected by the rotating part being sealingly connected with a sealing bell, and external sealing surfaces of the sealing bell, and external sealing surfaces of the sealing bell roll off on a fixed gasket flange.
