RADIAL PREMIXER - a liquid annular jet pump used as a prewetting device

Radial Premixer - Prewetting Device

RADIAL PREMIXER FEATURES

Premixes Liquids & Powders

Reduces Air Entrainment

Eliminates Dust

Pressurized fluid enters the prewetting chamber of the RADIAL PREMIXER tangentially and radiates outwardly to the wall of the mixing chamber. Powdered materials are introduced through a chemical hopper and are drawn into the eye of a strong vortex. As the particles are absorbed into the spinning fluid, the centrifugal force moves the mixture
outward providing distance between particles as the “wetting-out” process develops. The particle spreading caused by the centrifugal action completely eliminates particle adhesion or clumping associated with conventional mixing devices. Additionally, the centrifugal force
will eliminate air entrainment in the polymer. Clumps, fisheyes, and microgels visible on the surface of a mixing tank are caused by inadequate mixing.

The RADIAL PREMIXER uniformly distributes the powdered particles in a thin sheet of liquid enhancing molecular dispersion and promoting rapid polymer activation and fast clay hydration. The low contact time in the RADIAL PREMIXER ensures low shear to the mixture resulting in maximum product performance.

The LOBESTAR® MIXING EDUCTOR is a liquid center-drive jet pump, using a converging jet nozzle for a pressurized fluid to generate a high velocity to entrain an annular suction flow. The RADIAL PREMIXER is a liquid annular jet pump which uses a high speed converging annular jet nozzle to entrain a central suction flow. The combination of the two is the LOBESTAR® shear mixer. A couple configurations are illustrated below. Common uses are to Hydrate Bentonite, Solubilize Polymers and Barite Speed Mixing.
