Stirring uniformity of mixture depends not only on structural parameters of the mixer,motion parameters, but also to a large extent on the using parameters.Based on the analysis of the structure and working principle of mixer,these factors that affecting mixer performance was studied.The mathematical model of mixer performance characteristics was established by theoretical analysis,which associated with the mechanical structure, motion parameters and using parameters. According to the mathematical model,the effects of the mixer filling rate, stirring time,and other using parameters on the uniformity were studied. In each stirring cycle, the minimum number of revolutions formula for shaft was obtained. In addition,in different filling rates,the relationship between stirring shaft rotation laps and stirring uniformity was obtained too.Finally,full-scale experimental verification was conducted.
