双卧轴搅拌机搅拌过程的物料运动模拟

Motion Simulation of Mixture During Mixing of Twin-shaft Mixer

根据双卧轴搅拌机的特点,对物料的运动过程进行数学建模,研究了物料的周向循环、垂直上下运动、两轴间对流运动对物料拌和的作用,进一步分析了影响这三种物料运动的搅拌参数。结合试验,发现了叶片的面积、个数、安装角、排列顺序以及两轴叶片相位角等搅拌参数的最佳配合方式和取值范围。

According to the characteristics of twin-shaft mixer, the mathematical modeling for the motion of mixture was carried out to study the effect of motions including the circulation, vertical motion and convection motion between the shafts on the mixing of materials, and further research was conducted to find out mixing parameters that affect the motions. Combined with tests, the optimum matching and value range of mixing parameters are determined, including the area, amount, mounting angle and orders of blades and the phase angle.
