Static mixers are precision-engineered devices that serve in the continuous mixing of fluid materials with stationary components. The fluids that are mixed are usually liquid, but these mixers can also be utilized to mix gas streams, blend immiscible liquids, or disperse gas into a liquid. Read More...
Static MixersStatic mixers do not have any moving parts but use carefully designed ribbon-like obstructions within a cylinder to force the flow of material to mix and blend together.
Ross LPD/LLPD (Low Pressure Drop) and ISG (Interfacial Surface Generator) Static
Mixers are well proven for wide ranging uses in turbulent and laminar flow mixing
applications. These designs can be supplied as complete plug-in modules or as mixer
inserts designed to fit an existing pipe or tubing. If you have a current need for Static
Mixers, we would be happy to recommend a suitable model...
The Admixer series of sanitary static mixers and blenders is perfect for food, beverage & dairy processing. The Admixer delivers a 100% product uniformity and distribution from controlled shear and turbulence. It meets 3-A Standard #35-04 and is designed to process flow streams from 0.25 to 250+ GPM. The Admixer blends most combinations of flow, viscosity and density even from multiple incoming...
Static mixers are precision-engineered devices that serve in the continuous mixing of fluid materials with stationary components. The fluids that are mixed are usually liquid, but these mixers can also be utilized to mix gas streams, blend immiscible liquids, or disperse gas into a liquid.
The energy required comes from pressure loss as fluids flux through the static mixer. A static mixer consists of a housing pipe and mixing elements but does not contain any moving parts. Instead, the product is mixed by the flow through the mixer.
Static mixers consist of a rectangular plate twisted 180 degrees, creating a left element and a right element, depending on the twist direction. The basic length of an element is 1.5 times the length of the diameter.
How Static Mixers Function
The mixing element causes turbulence in the housing of the mixer, which will, in turn, mix the chemicals that are added either prior to the mixing or through the housing mixer’s injection port.
Within 3D of the mixer exit, the process media will be 95% mixed; this is known as CoV (Coefficient of Variation). The CoV targeted for static mixers is a coefficient of variation of 0.5 or 95% mixed at 3D from the mixer’s exit.
Static Mixer Installation
Static mixers can be flanged to fit in a pipe system. Static mixers can also come with plain ends; the customer supplies the fittings for the ends. They can also come with tri-clamp ends in the food and pharmaceutical industries.
The tri-clamp end connections mean that they can be removed from the pipeline with great ease for cleaning. Bolted flanges do not have to be removed.
Types of Static Mixers
The different types of static mixers include:
Double Roof Disk Static Mixer
This type of static mixer is utilized in the mixing, homogenization, and dispersion of viscous materials. It is a high-performance motionless mixer design capable of creating a very high degree of mixing within a very short period. It can mix materials that exhibit very large differences in volumetric and viscosity ratios.
Inclined Plate Static Mixer
This type of static mixer is utilized for the laminar flow mixing or dispersion of viscous fluids. It is also a high-performance mixer that can mix materials with extremely large differences in volumetric and viscosity ratios. It can mix thoroughly within a very short time.
Corrugated Plate Static Mixer
This type of static mixer is a high-performance and inline static mixer. It can mix liquids of low viscosity, blend gasses, disperse immiscible liquids and create gas-liquid dispersions within a short time but with an extremely high degree of accuracy.
Helical Static Mixer
This type of static mixer is cost-effective and exhibits moderate mixing performance capabilities. It is mostly used in small-diameter turbulent flow and laminar flow applications.
The mixing task is simple where its open geometric structure and low-pressure drop characteristic features are best for the specified application. Helical static mixers are available in plastic and metal construction in various configurations and sizes.
Applications and Benefits of Static Mixers
The different applications and benefits of static mixers include:
Applications of Static Mixers
Dispersing immiscible liquids like water and crude oil in refineries for extraction applications
Contact liquids and air for oxidation
Polymer processing and Manufacture
Media that contains high solids concentration
Paint and lacquer/dyes
Polyelectrolyte in wastewater
Benefits of Static Mixers
Highly efficient mixing
Minimal space requirement
Ease of installation
No need for tanks
Low energy consumption
No moving parts for maintenance; free operation
No requirement for direct motive power
