Difference Between Sag Mill vs Ball Mill

Oct 12, 2017· SAG mill make use of steel balls included with some large and hard rocks for grinding These mills utilize the balls in making the large fragments of materials broken into piec The ball charge of a SAG mill is about 9% to 20%This process takes place inside the large rotating drum of SAG mill which is filled with balls partially...

Addition of pebbles to a ball

The grinding circuit used for processing of gold, platinum and base metal ores typically consists of SAG primary mills, followed by ball-mills The power drawn by the ball-mills is about the same as that of the SAG mill for high capacity milling circuits Table 1 is an example of data for this type of circuit...

Ball Charge and Grinding Efficiency

Addition of pebbles to a ball

When the proportion of pebbles in the mill charge was low (up to 30%), the larger pebbles wore away significantly faster than expected, based on a constant surface wear rate This could be due to size segregation in the mill CITATION Nkwanyana S and Loveday B Addition of pebbles to a ball-mill to improve grinding efficiency...

Grinding Circuit

A typical SAG-HPGR-Ball mill circuit suggested by Patzelt et al [6] is shown in Figure 96, where the pebbles from the SAG mill are crushed in the high-pressure grinding rolls It is a general observation that SAG mills are helpful for grinding where wide variations in the grindability of ores are experienced...
