| Abstract: |
A static mixer head that provides not only distributive mixing, but also dispersive mixing. Distributive mixing is accomplished by providing a series of baffles along the length of the mixing tube, each baffle being angled relative to the previous baffle. Dispersive mixing is accomplished by utilizing baffles that define a converging pathway for the mixing materials. The converging pathway promotes elongation and corresponding dispersion of the mixing materials. In one embodiment, the baffles are teardrop-shaped, and are arranged so that multiple baffles are generally parallel and adjacent to one another. Preferably, the baffles are oriented such that the mixing materials flow from the small tail portion of the baffles toward the larger head portion of the baffles, thereby encountering a gradual compressive force and corresponding elongation.

What is claimed is:
1. A static mixer head for mixing materials, said mixer head comprising a plurality of rows of baffles, each row including a plurality of baffles and each baffle defining a longitudinal axis that is parallel to the longitudinal axis of another baffle in the same row, wherein the longitudinal axes of the baffles in one row are transverse to the longitudinal axes of the baffles in an adjacent row, and wherein each baffle includes:
- an upstream portion; and
- a downstream portion having a convex shape.
