context_page_description: In industrial process engineering, mixing is a unit operation that involves manipulation of a heterogeneous physical system with the intent to make it more homogeneous. Familiar examples include pumping of the water in a swimming pool to homogenize the water temperature, and the stirring of pancake batter to eliminate lumps.
  Mixing is performed to allow heat and/or mass transfer to occur between one or more streams, components or phases. Modern industrial processing almost always involves some form of mixing. Some classes of chemical reactors are also mixers.
  With the right equipment, it is possible to mix a solid, liquid or gas into another solid, liquid or gas. A biofuel fermenter may require the mixing of microbes, gases and liquid medium for optimal yield; organic nitration requires concentrated nitric and sulfuric acids to be mixed with a hydrophobic organic phase; production of pharmaceutical tablets requires blending of solid powders.
  The opposite of mixing is segregation. A classical example of segregation is the brazil nut effect.
context_section_description: Ribbon Blender
  Ribbon blenders are very common in process industries for performing dry-mixing operations. The mixing is performed thanks to 2 helix (ribbon) welded on the shafts. Both helix move the product in opposite directions thus achieving the mixing (see picture of ribbon blender).

  Planetary mixer
  A planetary mixer is a device used to mix round products including adhesives, pharmaceuticals, foods (including dough), chemicals, electronics, plastics and pigments.
  This mixer is ideal for mixing and kneading viscous pastes (up to 6 million centipoise) under atmospheric or vacuum conditions. Capacities range from 0.5 US pints (0.24 l; 0.42 imp pt) through 750 US gallons (2,800 l; 620 imp gal). Many options including jacketing for heating or cooling, vacuum or pressure, vari speed drives, etc. are available.
  The blades each rotate on their own axes, and at the same time on a common axis, thereby providing complete mixing in a very short timeframe.
  Banbury mixer
  The Banbury mixer is a brand of internal batch mixer, named for inventor Fernley H. Banbury.  The "Banbury" trademark is owned by Farrel Corporation. Internal batch mixers such as the Banbury mixer are used for mixing or compounding rubber and plastics. The original design dates back to 1916. The mixer consists of two rotating spiral-shaped blades encased in segments of cylindrical housings. These intersect so as to leave a ridge between the blades. The blades may be cored for circulation of heating or cooling. Its invention resulted in major labor and capital savings in the tire industry, doing away with the initial step of roller-milling rubber. It is also used for reinforcing fillers in a resin system.
