Double Roof Disk Static Mixer (Type GXR)

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.

Figure #2: Blue and white epoxy resin mixing test shows that an empty tube (left) provides no mixing. Eight (8) GXR mixing elements (center and right) create a homogeneous mix in a short length.

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 also available in inexpensive plastic construction (50% glass-filled Nylon and polypropylene)
