### Autogenous and Semi-Autogenous Mills - .

SAG mills of comparable size but containing say 10% ball charge (in addition to the rocks), normally, operate between 70 and 75% of the critical speed. Dry Aerofall mills are run at about 85% of the critical speed. The breakage of particles depends on the speed of rotation. Working with a 7.32 m diameter and 3.66 m long mill, Napier-Munn et al. observed that the breakage rate for the finer ...

### Ball mill - Wikipedia

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about ...

### SAG Mill Grinding Circuit Design

30.05.2020· However, the SAG Mill always works at a set energy usage rate; if a recipe requires less energy, the job will be completed faster. Therefore, 80% Power Use equals 25% faster processing speed. Bonus Output modifies chance-based outputs. The given percentage is applied to the base bonus output chance. For example, without a grinding ball, Diamond Ore is ground into two Diamonds, and has a .

### SAG Mill - Mining engineering - Eng-Tips

01.06.2005· I work at a copper mine that has a SAG mill with 5" balls. When we go in the mill for liner inspections, you can feel balls exploding underneath your feet. Last year my boss got cut in the ear by one. I always thought that the balls exploded due to the internal stress generated by the outside cooling (and shrinking) faster than the inside. If we wait long enough before entering the SAG mill ...

### COMMINUTION '10 - SAGDesign

ball mill work index (13 kWh/t) had SAG hardness as low as 1.4 kWh/t in one case (Aurora) and up to 34 kWh/t in the other case where NICO data was reported in January 2010 at the CMP in Ottawa. This proved that a Bond BM Wi alone must never be used for designing a SAG mill. The ratio of SAG hardness (to grind from F80 152 mm to T80 1.7 mm) divided by the Bond ball mill work index was .

SAG mills mimic the same shortcoming. It follows that in order to obtain the speciﬁ c energy (SE) to achieve a certain transfer size, based on the 80 per cent passing value, an inefﬁ ciency factor must be applied to the SE of single stage ball mills, rod mills or AG/SAG mills when calculating power according to the Bond Third Theory method. Rod mill and AG/SAG mill products are similar and ...

### How ball mill works?

The shape of drum liners has a significant impact on mill's work. Drum Liners of ball mills operated on a large source material have ribs. For mills operated on the fine materials use lining with small ribs or quite smooth. Height, mutual arrangement and shape of the ribs define force of adhesion the grinding media with the drum and the results of the mill's work. It is important when the ...
