permix jet mixers & dispersion mixers

---

A jet mixer is used where homogenizing, dispersing, suspending, emulsifying, dissolving are required. Its advantages compared with a conventional agitator are free of aeration, no floating powder, no sedimentation, no additional baffles, no flow dead zones, and very high efficient that a small motor can keep large volumes in motion. It is distinguished over ordinary blenders due to its very innovative Stator & Rotor assembly. Stator is a streamlined deflector tube fixed around the three-blade rotor. This design draws the liquid & solid into the tube and generates great turbulence there to mix and disperse those “Difficult-To-Disperse” powders into liquids, more cost-effective, and cutting process time up to 90%.

A jet mixer functions with its special designed stator/rotor system. The rotor is usually a turbine impeller, and the stator is a curved guide tube surrounding the rotor. When it works, the rotor generates a strong axial flow from the surface of the liquid, going through the stator tube and towards the bottom. In this manner, floating powder is drawn into the liquid, and sedimentation is lifted up. With many circulations, the total tank can be mixed and homogenized without dead zones. There are four steps to describe the working principle: 

Step 1. When the rotor runs at high speed (up to 3,000rpm @ 50Hz), strong vacuum is generated at its center. Liquid & solid above are drawn into the tube with the guidance of the deflector (stator). 

Step 2. Centrifugal force leads the materials to the periphery. Liquids and solids are subject to intensive squeezing and milling at the precision-machined clearance between stator and rotor. 

Step 3. For N agitator, materials are expelled out from the bottom of the tube back to the liquid body. For O agitator, a part of them will stand another intense hydraulic shear as they pass through the openings in the stator. 

Step 4. Fresh materials are continually drawn into the stator and rotor to maintain the mixing cycle in the tank. Two Types of Jet Mixer:There are two types of jet mixer available, and the difference lies in the stator (as shown in the picture). The stator can be either with or without openings. A jet mixer with a stator without openings has a stronger axial flow, because all the materials will go through the tube from the top to the bottom. But for the jet mixer with a stator with openings, some of the materials will go out of the tube through the openings. This makes it have some homogenizing ability.
