2015-12-16mill. As such, primary ball mills should be designed with the rod mill work index, and single-stage ball mills should be with both the rod mill and ball mill indices. This is because it is common to observe a difference sometimes significant between the rod mill and ball mill index values for a given ore type McKen, Verret, Williams, 2006. On
Metso has experience of over 8,000 grinding mills globally, including manufacturing and delivering the largest SAGAG mills in the world. Our experts welcome the opportunity to assist you with circuit and circuit control design as well as start-up, operation, and optimization of your mill.
Data from high mill loads, both in absolute filling and ball loading, have been used to extend and improve the JK SAG mill model. This improved understanding has been successfully applied to ...

2013-5-6It is 7 higher because the SAG mill grinds the softest components quickly and leaves the harder material to be ground in the ball mill. Figure 3 presents the graph of SAG pinion energy vs. BWi. The database supports a general trend between SAG and ball mill hardness for the majority of the test work data but the correlation is too low
Rely on our proven track record of SAG and AG Mill superiority. Since the early 1980s, we have been designing and manufacturing Semi-Autogenous SAG and Autogenous AG Grinding Mills under the Fuller-Traylor brand. Semi-autogenous grinding uses a minimal ball charge in the range of 6-15 while autogenous grinding uses ore only.
The SAG mill was designed to treat 2,065 t h 1 of ore at a ball charge of 8 volume, total filling of 25 volume, and an operating mill speed of 74 of critical. The mill is fitted with 80 mm grates with total grate open area of 7.66 m 2 Hart et al., 2001 .
difference between sag mill and ball mill SAG Mill - Semi-Autogenous Grinding Mill - Repair | FAB 3R A semi-autogenous grinding mill, or Sag mill, is responsible for grinding materials from large chunks into small, usable pieces for processing.

2020-3-22The two ball mill lengths given can only be correct if the ball mill are flat-ended. These mills are believed to have a cone end, so one of the reported values is incorrect. Another source, the 1999 SME paper by Dunne et al., gives the ball mill dimensions as 6.7 m 11.13 m or 22 ft 36.5 ft this suggests a belly length of 10.97 m and ...

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 size between the SAG mill and ball mill ...
