Design Development and Power Requirement Estimation of Conical Dual Blade Sinusoidal Mixer

Abstract

Stirring process is an integral part in manufacturing process of paints. Mechanical mixers are used largely in mixing of paints, semi-solids and jellies where in the suspended particles in form of powder or semi-solids are suspended uniformly to disperse the particles thoroughly to desired homogeneity .In cases predominantly where the specific weight of the powder is high the problem occurs the tendency to settle down poses a major problem in fixing such is the scenario in the case of production of ionic paint used for corrosion prevention , an thermal insulation in automobile silencers. These ionic paints require to mix metal powder rust (oxide) of heavy density in vehicles added with pigment base. Vehicle or base fluid is a low density evaporative fluid which is mixed with metal oxide powder to form thoroughly mixed applicant that can be applied by use of spray painting on to automobiles silencer to form a non-corrosive particle layer.
The project work is proposed to carry out the sizing, design development of conical dual blade sinusoidal mixer. The paper deals with estimation of the power requirements of the mixer and discusses over all constructional features of the mixer. The arrangement of the blades of the stirrer impeller is discussed along with the power train to drive the stirrer shaft
