A survey of 40 industrial mills in China found that the maximum ball mill diameter in use was 7.9 metres and length 13.6 metres. Autogenous mills range up to 11 metres in diameter. The length-to-diameter ratios indicated in Table 1 for ball mills are for normal use, but for primary grinding the ratio could vary between 1:1 and 1.8:1.

Whereas the ball mill energy was measured in the pilot plant, the crusher energy (either secondary or pebble) was estimated on the basis of the Bond model and the Bond crushing work index (Bueno and Lane, 2011). The crushing-ball milling circuit specific energy was estimated on the basis of the Bond equation and the relevant Bond work indices ...

A Ball mill works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A Ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It …

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.
