ABSTRACT:
A high capacity blender has been devised which is adaptable for use in achieving the proper blend of liquid-to-liquid or liquid-to-solid constituents making up a gel composition for use in fracturing oil and gas well formations in which a high speed impeller is mounted for rotation concentrically within an outer casing and has a solids inlet which is isolated from the liquid inlet. A series of liquid inlet apertures are disposed in outer concentric surrounding relation to the impeller, and impeller vanes within the impellers are operative to impart a centrifugal force to solids introduced therein whereby to direct the solids and materials radially and outwardly under considerable force into the liquid stream which is directed axially along the inner wall of a mixing chamber. A preselected amount of the blended materials may be recirculated through the impeller inlet, and varying amounts of the solids in proportion to the liquid may be introduced through the impeller region while assuring intimate mixing with the liquid stream in a single stage for introduction under the desired pressure for pumping into the well.
