In industrial ball mills, monitoring of girth gear and dual mesh pinion gearboxes are required for successful operation. In this paper, the dynamic response of an industrial ball mill is investigated through finite element analysis using ANSYS. A half symmetry model of the ball mill drive with anti-symmetry option is considered for the …
