Ball Mill Charge Volume Calculation. Ball Mill Charge Volume Calculation . The total volume inside the mill is given by Vm 4 D2 mL 1 2Lc L L 1 DtDm 3 1 DtDm 816 The density of the charge must account for all of the material in the mill including the media which may be steel balls in a ball mill
8.3.2.2 Ball mills. 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.
The mill product can either be finished size ready for processing or an intermediate size ready for final grinding in a rod mill ball mill or pebble mill. AGSAG mills can accomplish the same size reduction work as two or three stages of crushing and screening a rod mill and some or all of the work of a ball mill.

The starting point for ball mill media and solids charging generally starts as follows 50 media charge. Assuming 26 void space between spherical balls non-spherical irregularly shaped and mixed-size media will increase or decrease the free space 50 x 26 13 free space. Add to this another 10-15 above the ball charge for total of 23 .
