Working Operations of ball mill. In case of continuously operated ball mill, the material to be ground is fed from the left through a 60° cone and the product is discharged through a 30° cone to the right. As the shell rotates, the balls are lifted up on the rising side of the shell and then they cascade down (or drop down on to the feed ...

The critical speed of a rotating mill is the RPM at which a grinding medium will begin to "centrifuge", namely will start rotating with the mill and therefore cease to carry out useful work. Ball mills have been successfully run at speeds between 60 and 90 percent of critical speed, but most mills operate at speeds between 65 and 79 percent ...

Critical Speed_. When the ball mill cylinder is rotated, there is no relative slip between the grinding medium and the cylinder wall, and it just starts to run in a state of rotation with the cylinder of the mill. This instantaneous speed of the mill is as follows: N0 — mill working speed, r/min; K'b — speed ratio, %.

The reason for this variation in ball mill work index is because the ore at Mt. Milligan has an intrinsic exponent of in the 100 µm to 200 µm size range, not the exponent empirically measured by F. Bond. The work index increase between 100 µm and 76 µm is due to a porphyritic grain size that causes a spike in energy

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or times the drum diameter. Ball mills with a drum length to diameter ratio greater than are referred to as tube mills.
