Review on Design of Agitator to Optimize its Performance

Mixing is very important operation in any process industry. All operations involving liquid phase reactions, homogenization, emulsion, dissolution, extraction, need mixing in one form or other. Mixing of powders, pastes, paints jellies and many other products is needed to be done in many industries for many applications. In this paper, we have mainly focused on different parameters used for design of agitator including design of shaft, impeller blade, coupling, bearings, Hub and Keys. The design of agitator affects on the mixing process as proper design can increase the agitation and uniform distributions of all additives, chemicals, raw material presents in given agitator. The review drives us to design an mistake prone model for agitator which will increase the mixing percentage; ultimately increase the growth of industry to get right place into market with price for product. This review gives the complete information about agitator and parameters to be considered for design to enhance its performance.
