Abstract
The machine disclosed herein is useful for blending solids with fluids. In a typical operation, sand is mixed with a gel composition to obtain a fluid mixture suitable for stimulation treatments of oil and gas wells. The machine includes a slinger member, of a toroidal shape, and an impeller, of a vortex configuration, that is fastened underneath the slinger. In this machine entrained air is carried into the fluid phase by the sand, but the air is then 'exhausted' from the sand-gel mixture through interior and exterior air exhaust channels and spaces that are built into the machine.
