摘　　要：分析了立式改性沥青搅拌罐内物料流场的特性,并从桨叶的形式、分布、转速等方面分析了搅拌桨叶对流场的影响,得出优化搅拌罐桨叶设计的理论依据。并特别指出,在改性沥青类防水卷材生产线的配料系统中,应根据混合料黏度的差异,选择不同形式的搅拌桨叶。The article analyzes the characteristics of material flow field inside vertical bitumen modifying mixer and the influence of the blade on the flow field from blade form, distribution and rotating speed of the mixing blade, and acquires the theoretical foundation for the optimization of the mixing blade. It points out that viscosity of the compound should be taken into consideration when choosing the suitable type of the mixing blades for compound preparation system in membrane plant.
