caption = Three static mixers. At the top, an alternating spiral mixer (each spiral offset by 90°); in the middle, the same type of mixer in a delivery tube (such as forepoxy ); at the bottom, a larger metal mixer used to divide a flow into streams that intersect at 90°.

related =Magnetic stirrer Vortex mixer A staticmixer is a device for blending (mixing) two liquid materials. The device consists of mixer elements contained in a cylindrical (tube)or squared housing. The static mixer elements consist of a series of baffles that are made frommetal or a variety ofplastics . Similarly, the mixer housing can be made from metal or plastic. Typical materials of construction for the static mixer components includedstainless steel ,polypropylene ,Teflon ,Kynar andpolyacetal .The overall system design incorporates a method for delivering two streams of liquids into the static mixer. As the streams move through the mixer, the non-moving elements continuously blend the materials. Complete mixing is dependent on many variables including mixer length, tube inner diameter, the number of elements and their design.
A common application for static mixers include mixing two component adhesives (e.g.
epoxy ) and sealants (seeResin casting ). Other applications include wastewater treatment and chemical processing.
