Difference Between Sag Mill vs Ball Mill mech4study. 2017-10-12 SAG mill make use of steel balls included with some large and hard rocks for grinding. These mills utilie the balls in making the large fragments of materials broken into pieces. The ball charge of a SAG mill is about 9 to 20.This process takes place inside the large rotating
Difference between the two is that the ratio of steel balls to rock is Table 3 A summary of RoM ball and SAG mill test conditions. RoM BALL MILLS - A COMPARISON WITH AGSAG MILLING
Most mills used in mining rely on impact to breakdown rock to a suitable sie for downstream processing. The impact can be rock on rock such as in an Autogenous Grinding AG mill rock and a small ball charge 10 used in Semi Autogenous Grind

The operating cost difference between the two circuits is driven by the difference in ball mill steel wear between the SAGball mill circuit and the crushingHPGRball FL FL breaks world record in Chile. Before the Esperana order FLs largest SAG mill measured 38 and its ball mills 26
Factor of 1.25 that accounts for the difference in grinding efficiency of a SAG mill versus a ball mill. The original Barratt papers do not specify values to use for PC and PR but we can use the same values as Table 1 of 10 000 m and 2100 m respectively. The value T80 is the synthetic transfer sie between the SAG mill and ball mill
2017-12-14ondary ball milling. In these circuits the SAG mill is the largest energy consumer.
