The Planetary Centrifugal Mixer, Vortex Mixer, mixes hard to blend products utilizing centrifugal force. Unlike a centrifuge , which uses the forces to separate products by density, the Vortex mixer utilizes a unique dual axis design to mix hard to blend materials over a wide viscosity range. Materials are driven to the furthers part of the mixing container as it revolves around the center of the mixer. However, the angled mix cup is rotated at a fixed ratio to the speed of revolution. The furthest location in the mix cup continues to change due to the combination of the rotation and revolution. This change forces material in the cup to flow over itself, producing shear both at the container walls and within the product itself. Materials including polyurethanes, silicones, inks, waxes, caulks and sealants can be mixed thoroughly in under a minute.
