The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

Mill Critical Speed Determination. The "Critical Speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface. This is the rotational speed where balls will not fall away from the mill's shell.

Sag Mill Grinding Circuit Design. Sag mill vs ball mill since agsag mill volume is roughly proportional to the mill radius cubed at typical mill lengths while the available crosssectional area grows only as the radius squared pulp lifters must become more efficient at transferring slurry in larger mills mills with pebblecrushing circuits will require grates with.

Difference Between A Sag Mill And Ball Mill. The apparent difference between ball mill and agsag mill efficiency is an artefact of bonds implicit assumption that the particle size distributions can be defined by one point, the 80 passing size.In fact, bond noted that this convenient assumption was valid only in cases where the cumulative particle size distributions were roughly parallel.

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.

mill. 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
