Simulation of ball charge and liner wear - ScienceDirect

1993年10月1日  Specifically, it was possible to model and then to simulate ball charge and liner wear, two factors that determine ball mill non-stationary behaviour, using results from a ball charge motion model. The ball charge wear model incorporates adhesive and abrasive wear as a function of energy dissipated in crushing, tumbling and grinding zones of the charge motion

Predicting liner wear of ball mills using discrete element method

2022年6月1日  There are many experimental studies on liner wear, and various approaches have been proposed and implemented to increase the liner life (Banisi and Hadizadeh, 2007, Yahyaei et al., 2009).In particular, based on an experimental study, a liner wear apparatus was developed to monitor the liner wear effect on the grinding performance of ball mills (Powell, 1991).
