In an ultra-high-shear inline mixer, the high-shear mixing takes place in a single or multiple passes through a rotor–stator array. The mixer is designed to subject the product to higher shear and a larger number of shearing events than a standard inline rotor–stator mixer, producing an exceptionally narrow particle-size distribution.
The energy needed for mixing comes from a loss in pressure as fluids flow through the static mixer. [2] One design of static mixer is the plate-type mixer and another common device type consists of mixer elements contained in a cylindrical (tube) or squared housing. Mixer size can vary from about 6 mm to 6 meters diameter.
Micro-dosing systems with a quantity as small as 50 picolitres; Volumetric systems for use with adhesives and spraying systems for silicone coating needles and other surfaces; Microdispensing is also used in non-medical applications, like on-demand soda flavoring (the Coca-Cola Freestyle and Pepsi Spire), inkjet printing, and 3-D printing.
In such cases bubble free dispensing can only be obtained in vacuum. For this purpose dispensing systems are equipped with vacuum chambers. To shorten cycle times there can be an airlock at the entrance and one at the exit. In vacuum dispensing only systems where the parts are moving and the dispenser remains in place can be built reasonably.
Mixing of liquids occurs frequently in process engineering. The nature of liquids to blend determines the equipment used. Single-phase blending tends to involve low-shear, high-flow mixers to cause liquid engulfment, while multi-phase mixing generally requires the use of high-shear, low-flow mixers to create droplets of one liquid in laminar, turbulent or transitional flow regimes, depending ...
Mixer settlers are a class of mineral process equipment used in the solvent extraction process. A mixer settler consists of a first stage that mixes the phases together followed by a quiescent settling stage that allows the phases to separate by gravity.
