Agitators are utilized in a wide range of industries including chemical processing, paint manufacturing, water & waste water treatment, food processing, mining & minerals, oil & petroleum, pharmaceutical, biotechnology, soaps, cosmetics and much more. Agitators are used for a number of applications such as liquid blending, emulsification, heat transfer, crystallization, gas dispersion, absorption, washing or leaching, dispersion and dissolution.
An agitator is a type of mixer used for materials with low viscosities in low-shear applications. There are different types of machines that perform agitation such as magnetic agitators or manual agitators. A washing machine is also considered to be an agitator. As far as liquid blending is concerned, these machines are excellent for mixing two or more liquids. Agitators will mix liquid materials to create a uniform mixture. Since agitators are used for substances with low viscosities and most emulsions have high viscosities, emulsification applications require scraped wall agitators that work along side with a high speed disperser.
Agitation is a very important step to avoid particle from settling at the bottom of a tank. Dissolution is a sub-category of solid suspension which involves forming a homogenous phase from a solution of solid particles in a liquid. Solid suspension pertains to keeping a slurry of solid particles mixed within a liquid. Essentially, the main function of an agitator is to create a certain level of uniformity between two or more liquids (or solid particles) within a vessel.
