风槽的倾斜角度、气路的分布、气压大小以及粗精称蝶阀的控制等因素直接影响粉料的计量。本文介绍了风槽在混凝土搅拌站应用过程中,通过对倾斜角度的调整、气路的改变对粉料计量结果的统计分析对比,得出风槽气力输送设计时需考虑的因素。 Tilting angle of the trough, the distribution of the gas path, the size of the gas pressure and the control of the coarsely-defined butterfly valve directly influence the measurement of the powder material. In this paper, the application of the wind tunnel in the concrete mixing plant is introduced. Through the statistic analysis and comparison of the measurement results of the inclination angle and the change of the gas path, the factors to be considered in the design of wind power transmission are obtained.
