ABSTRACT:
Disclosed herein is an apparatus useful for blending solids with fluids. In a specific application of the blender, sand is mixed with a gel composition to obtain a fluid mixture suitable for stimulation treatments of oil and gas wells. Basic components of this blender are a slinger member and an impeller member, which are enclosed within a casing. The slinger and impeller are fastened together, with the impeller being positioned underneath the slinger. In addition, the slinger has a toroidal configuration and the impeller has a vortex configuration, and the slinger has a larger surface area than the impeller. The toroidal shape of the slinger, and its larger size, contribute to a good pressure balance within the fluid composition as it circulates inside the casing during the mixing operation. A more thorough mixing of the sand and gel composition is achieved by improving the pressure balance in the manner described.
