Abstract
A dynamic mixer includes a housing structure having a mixing chamber, having an inlet opening through which a material or materials to be mixed is passed into the mixing chamber and an outlet. A mixer rod has mixing rod portion disposed in the housing structure and a plurality of mixing paddle portions each having a mixing surface. The mixing rod is adapted for attachment to a drive unit which imparts a rotational mixing force to the rod. In one exemplary non-limiting embodiment of a mixer, the housing structure includes a hollow tubular structure with first and second open ends, a hollow T fitting having a first opening attached to the first end of the hollow tubular structure, a second opening opposed to and in alignment with the first opening and a third opening transverse to the first and second openings, and a coupler fitting attached to the second open end of the tubular structure. An end cap structure is attached to the second opening of the T fitting for supporting the rod drive portion for rotation and sealing against material leakage. A support structure is positioned at the second open end of the tubular structure and secured in place by the coupler fitting, to support t…
