Mixing is very important operation in any process industry. All operations involving liquid phase reactions, blending homogenization, emulsion preparation, dissolution, extraction, etc., need mixing in one form or the other. Mixing of powders, pastes, paints jellies and many other products is needed to be done in many industries for many applications; it can be done by the rigorous shaking and creating turbulence in the contents. The process is called as agitation for which directionally reversible mixtures are utilized. These reversible mixers Can give partial homogenization for more effective homogenization it is needed to design of a special purpose machine which gives cyclic reversal of the rotor and create more effective agitating turbulence. This project is about such a special purpose dynamic mixer designed and developed for a paint manufacturing industry .In this paper, the design and development of this machine is discussed in details, the results of this work are encouraging and giving better agitating performance over conventional method.
