The ball mill is the most common ore grinding technology today and probably more than 50 of the total world energy consumption for ore grinding is consumed in ball mills.

Chat Online### Magnetic Separation Techniques to Improve Grinding Circuit

The high unit capacity SAG mill/ball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs which has in turn made many low-grade high-tonnage operations such as copper and gold ores feasible. Future circuits may see increasing use of high pressure grinding rolls (Rosas et al. 2012).

ball mills in producing the final product (particles finer than 74 µm) was 55.38 and 44.62 respectively. That is the SAG mill produces about 10.76 more than the ball mill in the final product. The average consumed energy at SAG and ball mills to produce one ton of final product was 23.16 kWh/t and 36.05 kWh/t respectively.
