The GXR Static Mixer (Licensee of Bayer, AG) is used for mixing, dispersing and homogenization of viscous materials. It is a high performance motionless mixer design that creates a very high degree of mixing in a short length. It is capable of mixing materials with very large differences in viscosity and volumetric ratios. Mixing Capabilities Mix fluids with similar viscosity Mix high and low viscosity fluids (1 million : 1) Mix fluids with large differences in volumetric ratio (1,000 : 1) Disperse and mix polymers with blowing agents Thermal homogenization Viscosity homogenization Applications Two (2) component viscous materials such as Liquid Silicone Rubber (LSR), adhesives, polysulfide, sealants, epoxy resins, polyurethanes, etc. Plastics Injection Molding Plastics Extrusion Polymer manufacture and processing The mixing elements may be safely pressed out of the housing by pushing on the support ring which avoids any damage to the mixing grid The GXR mixing elements are presently also available in inexpensive plastic construction (50% glass-filled Nylon and polypropylene) Helical Static Mixer The HT helical static mixer pioneered the inline motionless mixing industry over 40 years. It is a cost effective static mixer design with moderate mixing performance capabilities. It is most suitable for use in small diameter turbulent flow and laminar flow applications where the mixing task is simple and where it’s characteristic features of low pressure drop and open geometric structure are best for the specific application. For difficult applications, the high performance GX static mixer is recommended for laminar flow applications. The Helical static mixer is available in metal and plastic construction in a wide variety of configurations and sizes.

The GX static mixer has been used successfully for the laminar flow mixing and/or dispersion of viscous fluids for over 35 years. It is a high performance static mixer capable of mixing materials with equal or very large differences in viscosity and volumetric ratio. Mixing is accomplished in a short length with a very high degree of mixing. Mixing Capabilities Mix fluids with similar viscosity Mix fluids with high and low viscosity (1 million : 1) Mix fluids with large differences in volumetric ratio (1,000 : 1) Disperse and mix polymers with blowing agents Thermal homogenization Viscosity homogenization Applications Polymer manufacture and processing. Two (2) component viscous materials such as Liquid Silicone Rubber (LSR), adhesives, polysulfide, sealants, epoxy resins, polyurethanes, etc. Plastics Extrusion Materials of Construction, Housings and End-Connections The GX static mixer can be supplied in most materials of construction, pipe/tube housings with virtually any end connection (Figure #13). GX-P mixing elements in 9.3 - 9.4mm outside diameter size are also available in plastic construction. History of GX Static Mixing Structure The GX static mixer was invented by Bayer AG of Leverkusen, Germany in the mid 1970’s. Bayer used the GX static mixer extensively in their polymer plants and subsequently licensed the design to Sulzer Chemtech of Winterthur, Switzerland who trademarked the design as the SMX* static mixer. Sulzer did a tremendous amount of fundamental high quality R&D work on the SMX structure and commercialized the SMX static mixer in tens-of-thousands of successful installations. The founders of StaMixCo held key technical and management positions in the Koch Engineering (the later Koch-Glitsch)-Sulzer Chemtech team that commercialized the SMX static mixer. Bayer licensed their 2nd generation of the SMX static mixer to StaMixCo which is branded as the GXR structure with integral support ring around the X-Grid mixing bars as described in a previous section of this web site. * StaMixCo is not a distributor of or affiliated with Sulzer Chemtech. SMX is a brand and trademark of Sulzer Chemtech.

StaMixCo manufacturers all three commercially proven static mixer designs used for high viscous melt flow mixing of polymers in extrusion service. As with most process equipment, each static mixer design has specific advantages and disadvantages that make it more or less suitable for a specific application and installation. Each type of motionless mixer is discussed below: Process Improvements: Temperature gradients are virtually eliminated. Viscosity gradients are virtually eliminated. Composition gradients of colorant, chemical additives, fillers and regrind are virtually eliminated. Stagnant polymer wall-creep material is incorporated into the bulk polymer stream. Extrusion Applications Static Mixers are used in most extrusion applications including the following: Sheet Blown Film Foam sheet Profile extrusion Co-extrusion Pipe Extrusion Blow Molding Rod & Tubing Wire & Cable Coatings Fiber extrusion & monofilaments Benefits Reduction of color additives with comparable extrudate color density. Even thickness across the entire extrudate width. Streak-free product. Improved quality when using regrind material. Foam cell size and cell distribution uniformity. Improved surface quality Improved mechanical characteristics. Rapid color change-over SMB-R Static Mixer SMB-GXS Static Mixer Mixing of blue and white epoxy resin with the SMB-GXS Static Melt Blender. It improves the melt homogeneity by factor 5-6. SMB-R Static Mixer The SMB-R static mixer for extrusion service (licensee of Bayer AG, Leverkusen, Germany) contains eight (8) very efficient motionless mixing elements that homogenize the polymer melt as it enters the extruder die. The SMB-R mixing elements are considered as high performance design where they create a very high degree of mixing in a short length. The SMB-R mixing elements are virtually indestructible due to their monolithic cast construction where the mixing bars are jointed to each other and to the ring wall via a single molten metal pour. Mixing of blue and white epoxy resins. Empty tube (top)provides no mixing. Eight (8) mixing elements (bottom) provide an excellent mix quality in a short length. SMB-GX Static Mixer Melt Blender The SMB-GX motionless mixer is a design that has been used in melt flow mixing extrusion service for over 25 years. The SMB-GX mixing elements are considered as high performance design where they create homogeneous mix in a short length. It has the same fundamental X-Grid crossing-bar structure as the StaMixCo SMB-R static mixer (Figure #8), but without the support ring around the mixing blade structure which gives the SMB-R its remarkable strength. Since the SMB-GX is manufactured from metal plates that are welded together, virtually any custom static mixer plate thickness, material and diameter can be fabricated to meet process and installation requirements. SMB-H Static Mixer Melt Blender The SMB-H Helical static mixer design pioneered the static mixing industry and has been used as a viscous static mixer on extruders for over 37 years. The Helical design is considered a low mixing performance-long length-low pressure drop motionless mixer as compared to the later developments of high performance static mixers such as the SMB-R and SMB-GX which have become the technology standards in the industry. StaMixCo manufactures SMB-H static mixers by advanced proprietary manufacturing technique where the entire unit is machined from a solid rod of bar stock material without welding. This machining process allows for custom static mixer fabrication in virtually any L/D twist, in very small sizes, with very high strength, straight and true dimensioning and with a RMS 12 mirror polish surface finish which is a much improved surface finish as compared to the traditional 32 RMS finish for the twisted and welded design.
