#### Ball Mills - an overview | ScienceDirect Topics

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.

#### CALCULATION OF THE POWER DRAW OF DRY .

Calculation of the power draw of dry -compartment ball mills 225 The mill load that is the volume of charge in the mill is the principal determinant of power draw. Estimation of the ball load that is mixed with the cement charge is difficult and can be highly erroneous. So direct measurement must be taken for calculation of mill load.

[PDF]#### Size reduction by milling

A typical ball mill has a cylin-drical shell slowly turning about a horizontal axis. The shell is filled to about half its volume with a solid grinding medium. The grinding medium can be metal rods, chains or balls. In a ball mill, most of the size reduction is done by impact as the balls drop from near the top of the shell.
