    sph, dem, fem, tumbling mills. wet grinding of minerals in tumbling mills is a highly important multiphysical process in the mining industry. To create a numerical model that include pulp fluid and its interaction with both the grinding balls and the mill structure is an interesting challenge. during grinding inthe energy efficiency of tumbling mills can be examined directly by looking at the motion of ore and grinding balls inside the mill. the makeup of the charge and the lifter bars attached to the inside of the mill shell can be designed particularly to maximize the mass of ore fractured per unit of energy spent.
