Abstract
A method and apparatus for a mobile twin shaft mixer, which includes a mixing chamber formed of a flexible sheath and a frame formed of a rigid material. A benefit to the mobile twin shaft mixer can be a compact, lightweight, high capacity twin shaft mixer useful for mixing, proportioning, and transporting construction materials in mobile operations. A benefit to the methods of use of the mobile twin shaft mixer can be the supply of modern construction materials to the delivery location at the point of installation.
Claims17
A twin shaft mixer comprising:
- a frame formed of a rigid material, wherein the frame includes a dual mixing support structure and a sheath support structure;
- two mixing shafts, wherein an entry end and an exit end of the mixing shafts are supported by the dual mixing support structure;
- a sheath formed of a flexible material, wherein the sheath includes a top portion and a bottom portion, and the sheath forms a mixing chamber around and along a length of the two mixing shafts;
- wherein the top portion and the bottom portion of the sheath are attached to the sheath support structure, and wherein the mixing shafts include at least one blade having an outer edge,
- wherein the sheath support structure includes at least two sheath attachment strips extending along a length of the frame, wherein each sheath attachment strip includes a plurality of sheath attachment points extending along a length of the sheath support structure;
- and
- a plurality of rib attachment points extending along the length of the sheath support structure, and a plurality of ribs formed of a rigid material having rib ends and extending along a width of the mixing chamber, wherein the rib ends are attached to the rib attachment points.
