Simulation of Size Reduction in Ball Mills and DEM. The 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
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and maximum and finally the type of circuit open/closed ...

2D Model for Ball Mills Scientific.net. This work develops a mathematical model that explains the ball mills operational speed. The scope of the model is defined by the powder as the number of particles per cm3 and the Relevance defined as the ratio between different forces.
Ball mill definition, a grinding mill in which the material to be ground is tumbled in a drum with heavy balls of iron, steel, or stone. See more.
The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent. It is especially difficult to teach mill ...

The results of discrete element method simulation were compared with actual grinding experimental results. The grinding rate constant K can be expressed as K=a exp(bn), where n is the rotation speed. To investigate the correlation between K and the simulation results, a new factor, the calculated force, was defined as F cal =average force acting on a ball coordination number.
