Typical construction materials for static mixer components include stainless steel, polypropylene, Teflon, PVDF, PVC, CPVC and polyacetal.[3] In the housed-elements design the static mixer elements consist of a series of baffles made of metal or a variety of plastics.Complete mixing depends on many variables including the fluids' properties, tube inner diameter, number of elements and their design.[6] The static mixer traces its origins to an invention for a mixing device filed on Nov. 29, 1965 by the Arthur D. Little Company.The plate type static mixer patent was issued on November 24, 1998, to Robert W. Glanville of Westfall Manufacturing.
Depiction of how flow division and radial mixing can occur in a static mixer
Flow division in a static mixer that uses baffles is a function of the number of elements in the mixer
