Mixing of two or more materials or compounds i.e. heavy density metal powder in the fluid is a complicated task. In traditional mixing method the metal powder and fluid mixing is carried out on uni-directional stirring machine. This paper investigates the limitations of the traditional mixer. The stirrer of traditional mixer rotates in one direction only which create a particular and limited flow pattern in the fluid hence particles tend to stick to the wall of container due to the centrifugal force. Most of the materials are settle down at the bottom of the container due to high density. In traditional mixer, the other main issue is the vibrations, thrust and bending forces that create too much noise and high machine maintenance. The research work is based on the Schatz geometry shaker mixer mechanism which is used for a homogeneous mixing of powder substances with differing specific weights and particle sizes. The product is mixed in its own closed container. The mixing container is set into a three dimensional (3D) movement that used for rotation, translation and inversion according to the Schatz geometric mechanism theory. It is design as well as Finite Element Analysis (FEA) of driving system of Schatz mechanism with Three Dimensional motion mixer to produce desired motion pattern, increase mixing rate and quality by finding productivity effectiveness by using CATIA V5R20 and ANSYS.
