Get PriceThe mill with 30 cm in diameter and 30 cm in length and the test conditions are standardized with a maximum ball size of 40 mm and an ore top size of 3.35 mm. With less than 300 balls it poses no challenge in running the simulations if only grinding media are included. For such a small mill one could also include the ore or powder charge.

Get PriceDiscrete element DE simulation of a ball mill with a large number of particles is challenging when each particle is considered.
Get PriceJan 01 2018 DEM is a suitable tool for the study and characterization of ball mill behaviour since it is a numerical technique especially intended to simulate interacting particles. The DEM algorithm models the collisional interactions of particles using a contact force law and resolves the particles motion using Newtons laws of motion.
Get PriceAs our RampD 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.
Get PriceIn this work the milling operation of ball mills is investigated using two methods i.e. DEM and combined DEM-SPH. First a pilot scale ball mill with no lifter is simulated by both methods. Then another pilot scale ball mill with eight rectangle lifters is simulated again by both methods.
Get Price1 Abstract Discrete element DE simulation of a ball mill with a large number of particles is challenging when each 2 particle is considered. Similarity principle could be adopted to reduce the number of particles in a simulation whilst 3 still maintaining the accurate flow behaviour of particles.
