Structure Design Research for Concrete Mixer Blade

Abstract:

Aimed at the problems of logarithmic spiral blade mixing unequally and square spiral blade discharging in slow speed, a new method for deriving mixing drum spiral blade was proposed based on the principle of differentiation, deducing both logarithmic spiral and square spiral. Combined with actual demand, a new type of mixing drum spiral blade was designed. Compared with traditional spiral blade, helical lead angle of the new spiral became smaller in a certain range. The variation scope of pitch and taper section diameter were more reasonable, and then the mathmatical model of new mixing drum had been established.
