Descrierea matematică a dependenţei rezistenţei la amestecare în malaxoarele cu bare de coeficientul de umplere a tobei şi diametrul barelor

Abstract

Using the D-optimal plan for two factors, experiments were made to determine the dependence on resistance in the headway of mixer with working bodies in the form of bars of coefficient of the drum fill and the bar diameter. The regression analysis of the experimental data led to obtaining of the second degree polynomial, which adequately describes the investigated process. A nomogram has been built that allows rapid determination of drag resistance according to factor values.
