Ball Mill Simulation and Analysis. This video shows the inside of a Semi Autogenous Grinding (SAG) mill, a key machine for grinding crushed materials in mining. Optimize your SAG Mill operation using EDEM tools for analyzing the motion of rocks and balls, power consumption, wear and ball particle distribution through time.
ROCKY DEM is helping us to improve various processes. The use of simulation tools can quantify the design improvements and gains; this is advantageous because mining uses large equipment that without computer simulation can cost millions for prototype development and testing.
A method for simulating the motion of balls in tumbling ball mill under wet condition is investigated. The simulation method is based on the three-dimensional discrete element method (DEM) and takes into account the effects of the presence of suspension, i.e., drag force and buoyancy. The impact energy on balls' collision, which enables us to [.]
cific impact energy of the balls calculated from Discrete Element Method simulation. This relationship was successfully used for the scale-up of a rocking ball mill, and the optimum design and operating conditions for the rocking ball mill could be estimated by the specific impact energy of the balls cal-culated by a computer simulation.
That is, unless we can describe explicitly particles breaking simultaneously as the DEM simulation evolves, we stand little chance to move towards predicting performance of these machines. In the case of ball mills, this is certainly not straightforward.
