Abstract:This paper begins with the mechanism and purpose of the mixing motion. When working,the materials moves along the spiral surface,under the pressure of the blade,crumbles,rolls and twiste as a result of the opposite turning direction of the two axle,achieving the mixture effect of the concrete. It has been proved in the long-term production, through the horizontal Coaxial mixer surface of the leaf structure and shape of a reasonable layout and design, concrete’s quality and production efficiency will be greatly improved Combining with the advantages of three leafs, Concrete is going to mix as much as possible in the limited time through their orderly, rational layout. I do some theoretical analysis and a number of tests for the leaf-surface’s shape. Though the new design test, it overcomes shortcomings of traditional mixer, and notes that the new design may cause new problems.Though the theoretical analysia of the mixing process of the concrete,This paper explanins the selection of all confficient and gives conclusions and suggestions based on the theoretical analysis.
Key words: concrete mixer; double horizontal shaft;blade
