Energy Efficiency Analysis of Copper Ore Ball Mill Drive Systems
mdpiHow to choose a ball mill drive system for copper ore comminution?Conclusions The choice of a drive system for a ball mill used in copper ore comminution is largely dictated by the energy-related criteria. The energy efficiency of the three analyzed drives was identified in Monte Carlo simulations, which allow predictions of the most probable energy-consumption indicators.Energy Efficiency Analysis of Copper Ore Ball Mill Drive Systems
mdpiCan a fluid coupling control a ball mill start-up process?Energy Efficiency Evaluation of the Analyzed Drive Systems The simulations confirm that the application of a fluid coupling in the new drive system allows control of the ball mill start-up process. However, a complete analysis of each drive variant should also importantly involve the energy aspect.Energy Efficiency Analysis of Copper Ore Ball Mill Drive Systems
mdpiDoes ball size distribution affect mill performance?In the experiment, mono-sized balls of 80 mm were compared with a binary ball size containing 60% of 60 mm and 40% of 80 mm. The binary charge produced a product with more fines of less than 75 µm, by 4%. Therefore, studies show that ball size distribution affects mill performance.A Review of the Grinding Media in Ball Mills for Mineral Processing

Ball Mill
Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel.
The Ore Grade and Depth Influence on Copper Energy Inputs
This warrants the first conclusion: Statistically Eq. ( 4) is the best model for mines with milling/flotation. On the basis of this, an ore grade of 0.5, 0.4 and 0.3% at 300 m of depth results in an energy cost of 60, 127 and 447 MJ/kg for underground mines, and 52, 95 and 255 MJ/kg for surface mines, respectively.
