In this paper a comparative study concerning four classes of powder mixing systems is presented. Several factors such as; filling sequence, loading conditions, material dimensions and chemical characteristics are taken into account.In particular, a thorough analysis of mixture quality and power adsorption is carried out. A number of experimental tests are executed, varying the operating conditions and the powder characteristics. In this way factors such as mixing time, revolutions per minute, chamber volume, mixture composition and Froude number are taken into account.The experimental results are reported graphically and show, among other things, the influence of revolutions per minute on standard deviation and mean value of mixture quality. The power adsorption is also reported, as a function of Froude number and mixture composition.The result obtained can be useful for powder mixing system selection and the optimization of mixing parameters.

Abstract

In this paper a comparative study concerning four classes of powder mixing systems is presented. Several factors such as; filling sequence, loading conditions, material dimensions and chemical characteristics are taken into account.In particular, a thorough analysis of mixture quality and power adsorption is carried out. A number of experimental tests are executed, varying the operating conditions and the powder characteristics. In this way factors such as mixing time, revolutions per minute, chamber volume, mixture composition and Froude number are taken into account.The experimental results are reported graphically and show, among other things, the influence of revolutions per minute on standard deviation and mean value of mixture quality. The power adsorption is also reported, as a function of Froude number and mixture composition.The result obtained can be useful for powder mixing system selection and the optimization of mixing parameters.
