ABSTRACT


The paper presents results of modelling of quality changes in a muliticomponent non-homogenous granular mixture during mixing in an industrial worm mixer. The analysis was carried out for three granular mixtures: nine-component, ten-component and twelve-component. Modelling was performed with the use of nonlinear regression. Dependent variable was a residual sum of squares (mixture quality parameter), whereas independent variables were: number of components and mixing time. Two-dimensional dependence was constituted by square function formula. The aim of the study was to describe quality changes of muliticomponent, non-homogenous granular mixtures (nine, ten and twelve – component) during mixing in a vertical mixer with worm agitator, with the use of nonlinear regression model. Atypical aspect of the mixing process was a specific recirculation of the mixed components with the use of bucket conveyor during the process.

Key words: granular materials, granular mixture, muliticomponent granular mixture, residual sum of squares, nonlinear regression.
