Research highlights DEM used to simulate the dynamics of ball motion in an industrial scale ball mill. Energy distributions with progressively worn lifter geometry profiles were simulated. A basic wear model based on detailed DEM output data is proposed. DEM simulated energy data was utilised to predict breakage rates of fine particles. A simplified breakage rate model was developed to ...

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.
Numerical modelling based on DEM has been performed on ball mills of different sizes. It has been shown that the grinding of ball mills of different sizes follows the first-order kinetics. Although different collision environments exist with different sizes of mills, impact energy is a useful index that determines the grinding rate.
As our R&D colleagues commissioned more and more DEM simulation over the past few years, we needed to look for new, powerful and easy-to-use software. To help us react more quickly to these needs and work more efficiently, we chose Rocky DEM, a software with comprehensive functionality as well as a mature and proven user interface.".

Simulation Of Size Reduction In Ball Mills And Dem. Another reason for the early success of dem in tumbling mill simulation lies in the fact that the most common grinding media are balls typically made of steel and other ferrous alloys as such the common simplifying approach of using spheres to describe particles that makes life simpler in dem is not a problem since this is basically their

For the later 2-way coupled DEM + SPH phase of the simulation, the slurry/media flow inside the mill equilibrates within 3.5 s of simulation time and (following an initial surge of slurry out of the mill and through the trommel to the discharge end) the flow inside the trommel becomes quasi-steady by 4 s.
Moreover, the results obtained from DEM usually should be validated with experiments. In this paper, simulation results of particle behaviour, mill torque, and power consumption obtained from DEM simulation are compared with experimental results in detail to …
