Inline High Shear Mixer

The inline high shear mixer is a kind of equipment for large-volume rapid mixing. It can quickly mix a variety of different substance phases (gases, liquids, and solids) together. This mixer type uses a strong mechanical shear force for mixing, rather than relying on the material’s own flow to achieve mixing. Therefore, an inline high shear mixer has higher efficiency than a usual agitator. Moreover, it can complete a series of tasks such as dispersing, emulsifying, and crushing at the same time during mixing.

SeFluid has been a leading manufacturer of high shear mixers for 20 years. Our professional engineering team has years of extensive experience and can match pipeline high shear mixers with the most suitable parameters based on the actual operating conditions of our customers.

How Inline High Shear Mixers Work?


Inside an inline high shear mixer, there is one or more rotors fixed on the shaft. Each rotor corresponds to a stator. The gap between the stator and rotor is less than 0.5 mm. On the stator and rotor, there are interlocking teeth and there is a gap between the teeth. When the stator rotates at high speed, it generates a strong centrifugal force and leads to a negative pressure to draw the fluid into the work head. 

When the fluid enters the gap between the stator and the rotor’s teeth, it is strongly sheared, homogenized and emulsified together with the surrounding medium, finally achieving a good mixing effect and being discharged from the discharge outlet.

Features of Inline High Shear Mixer

100% Mixing and No Dead Spots

Usual agitator may form sludge and settle at the container bottom. Moreover, it is hard to mix materials with different physical gravity such as water and oil. By using a SeFluid’s inline high shear mixer, the external cycling, strong shear and mechanical kinetic energy can mix the fluids well. So, it is easy to avoid the agitator’s shortage. There will be full mixing and homogenizing.

Better for High Speed Dissolving

The mixer can make solubilizing to have higher efficiency. When the high-speed rotor sucks liquid and solid materials into the working chamber. The fluid will experience intense targeted shear in rotor/stator assembly. With each pass, the particle size will become smaller. Then the surface area of particles increases to the surrounding liquid and speed up the solubilization process.

Mixing Fluids with Different Viscosity

If blend miscible liquids with similar viscosities, an agitator will be suitable. But sometimes there is a big difference in viscosity between blended liquids. The liquids may move around, yet there is no actual blending between them. Moreover, it will take a long time to get a good blending. SeFluid’s inline high shear mixer series mixes the fluids rapidly and blend fluids almost instantaneously in a single pass. It is very suitable choice for continuous dilutions.

With Self-pumping Ability

In conventional mixing, there is a pump for feeding raw materials. Feeding pumps may cause excessive energy consumption, leak, or a mismatch between pumping and mixing capacity. Consequently, poor mixing performance or even jamming will happen. In our inline high shear mixers, the shearing parts generates strong centrifugal force to draw the fluid into working chamber and can pump the fluid up to 20 meters, no need of feeding pump.

Better for Emulsion Making

To make the droplet size as small as possible is very important. More shear energy will get smaller suspended droplets and a better stable emulsion. SeFluid’s inline mixer series is very ideal for this application. It can easily obtain an emulsion with a droplet size of 2 to 5 microns, even smaller size down to 0.5 microns also can be get based on different formulations. We produce all types of high shear mixers for making of emulsions.

Stage of Inline High Shear Mixer

For an inline high shear mixer, one stage means a pair of stator and rotor. A single stage means that the machine has only one pair of stator and rotor in the working head. Similarly, three stages mean three pairs of stators and rotors in the working head. For each stage, the medium is sheared and mixed at least once. Usually, the more stages mean the more times the fluid is sheared, the finer and better the final mixing effect. At the same time, the flow rate is also lower, because the kinetic energy of the fluid is lost with each mixing. Therefore, the selection of stage quantity should be based on the characteristics of processed fluid.

Accessories of Inline High Shear Mixer

In addition to the shear components, an inline high shear mixer has some other important auxiliary components that are critical to the mixing process.

High Efficiency Heating / Cooling Jacket

First, in the mixing process of some special materials, such as in the production of modified bitumen, high temperatures are required to keep the bitumen liquid, while in the mixing process of biological agents, lower temperatures is necessary. Therefore, in some special applications, there is a jacket layer round the working head for heating or cooling, with high temperature liquid or cooling liquid circulating to meet different mixing application needs.

Valve for Sampling and Draining

Secondly, after each batch of mixing work is completed, there will be a certain amount of residue left in the working chamber, which may deteriorate over time and thus affect the next batch of production. In addition, during the closed production process, the user may need to take micro-samples at any time to observe the mixing effect. Therefore, there are additional small drainage ports with valves on the working head for draining or sampling.

SS304 Splash Protection Cover (optional)

Moreover, in certain industries with high hygienic requirements, such as food, beverage, pharmaceutical, cosmetics, etc., a stainless steel splash production shield is necessary to the cover the motor to prevent contamination or corrosion of the machine by spilled liquids and to facilitate the cleaning of the inline high shear mixer. Meanwhile, At the same time, this shield can effectively protect the operators of the production line and prevent accidents.
