Study On Mixing Arms Arrangement And Blade Shape Of Twin Shaft Mixer

The concrete as the main building materials of infrastructure construction in modern society, the requirement of its quality and efficiency is higher and higher. Due to the high mixing efficiency and quality, the double-shaft forced mixer has become the most popular concrete mixing equipment in modern construction. However, because of its complex structure, the mixing efficiency optimization study is very difficult. The most design of mixer relies on experience at home and abroad.This topic on the basis of the old host JS1000 according to its existing shortcomings make the optimization goal. On the optimization of the transmission device, stirring device parameter selection for analysis and calculation. When designing the values from the perspective of the mixing mechanism, analysis of material particles in the process of the movement and changes in form, affect host mixing efficiency of the main structure parameters, including stirring arm number and decorate a form, mixing blade installation Angle, the drum length to diameter ratio, stirring shaft speed, etc. Selection to determine the optimal design values:mixing device parameters for parallel flow arrangement, layout, are arranged, the phase Angle of 60 degrees, stirring arm eight, mixing blades linear velocity 1.6 m/s, blade installation Angle of 40 degrees.By fluent software to optimize the flow field of two kinds of mixing for the host before and after the simulation analysis, to determine whether the new host optimization goals are met. Passed in test of prototype test results verify the correctness of the optimization parameter selection.Again to determine its optimization effect via Industrial validation.This topic through theoretical analysis, the fluent software simulation analysis and test prototype test to confirm each other, both played a theoretical analysis and software simulation is not affected by the advantage of the experimental conditions, and overcome the limitations of the idealized model, at the same time reduces the test the large amount of investment and reduce the test time, obtained the very good optimization effect, for the design of new twin-shaft compulsory mixer development provides a good method, and provides some theoretical basis and experimental data. Effects are verified through the site actual use, and to determine the product optimization has been a success.
