WebAbstract: As one of the machines widely used in mining, a semi-autogenous grinding (SAG) mill can significantly improve the roughing efficiency of rock. But the SAG mill still faces …
If you use very soft rock in a SAG mill it will not work as well as if you use harder rocks. Adjustments to the lifting plates around the circumference of the mill provide …
The impact of the shape representation used for rock particles in a DEM model of a SAG mill on charge dynamics and energy utilisation is investigated. A 1.8-m …
The SAG mill performance is researched based on the DEM-EMBD coupling method. •. The influence of dynamic characteristics of the SAG mill is considered. •. The …
A SAG mill grinds through the impact of rock and grinding media, while an autogenous mill grinds only through the impact of rock. An autogenous mill is more …

The model is optimized considering a yearly cost function, with hourly resolution for the solar irradiance and hardness models. The results show that integrating solar power into the …
This work analyzes the process of grinding rock in SAG mill and the wear of lifters. The discrete element method (DEM) was used to simulate the grinding of apatite …
