A high-shear Stirrer mixer, or transports, one phase or ingredient (liquid, solid, gas) into a main continuous phase (liquid), with which it would normally be immiscible.
A rotor or impeller, together with a stationary component known as a stator, or an array of rotors and stators, is used either in a tank containing the solution to be mixed, or in a pipe through which the solution passes, to create shear. A high-shear mixer can be used to create emulsions, suspensions, lyosols (gas dispersed in liquid), and granular products. It is used in the adhesives, chemical, cosmetic, food, pharmaceutical, and plastics industries for emulsification, homogenization, particle size reduction, and dispersion.
These high speed stirrers are widely used in printing inks industry like flexo and gravure where the resin part has to be per- mixed properly before adding into the attritors for grinding. These stirrers are also used for final thinning down of the ground printing ink etc. The motor with the housing and bearings are connected to the shaft with cowbell blade at the bottom. Side supporting rods are given with plate above so that the machine can be easily put in the vessel for mixing. Hook is provided on the top for hanging the stirrer. Once the material is ready after thinning down, the stirrer can be easily lifted up and taken to the next vessel for mixing after thorough cleaning of the stirrers.
