D Modeling Of Ball Mills

Abstract the paper presents an overview of the current methodology and practice in modeling and control of the grinding process in industrial ball mills basic kinetic and energy models of the grinding process are described and the most commonly used control strategies are analyzed and discussed

Of motion for each in a ball mill the collisions between two balls or a ball and the mill wall are expressed by a voigt model that expresses elastic spring spring coefficient k where elastic and inelastic properties of the objects are introduced between the points of contact as shown in fig 1and the viscosity dashpot damping coefficient
