Energy Efficiency Analysis of Copper Ore Ball Mill Drive ...
Milling is among the most energyconsuming technological stages of copper ore processing. It is performed in mills, which are machines of high rotational masses. The start of a mill filled to capacity requires appropriate solutions that mitigate the overloading. One method for increasing the energy efficiency of ball mills is to optimize their drive systems.

Flexible milling and grinding solutions that last | FL
For the mining industry, our semiautogenous (SAG) grinding mill uses a minimal ball charge in the range of 615 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media.

The ore first enters the ball mill circuits which pulverize the ore to sand. From the ball mills, the slurry is piped into flotation cells which float a mixed copper and molybdenite concentrate, which is piped to a second flotation circuit where the molybdenite and copper concentrates are separated.

What's the Difference Between SAG Mill and Ball Mill ...
· The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
