The predominantly radial movement move only a small portion of the solid particles.

The solid particels are radially thrown against the wall of the vessel. They turn radially with the liquid and sedimentate in the center. A vortex sucks in enormous amounts of air, creating foam.

The radial flow causes the components to separate. Because of this design, homogeneous mixing without air entrainment is impossible.

The solids are homogeneously suspended. Sedimentation and air entrainment are eliminated.
