Apr 11, 2017 The grinding balls bulk weight (steel density 7.85 t/m3). Thus, during calculating the grinding balls mass in ball mill (after measuring the mill filling degree with grinding media) needs to use the grinding balls bulk weight whose diameter was determined earlier.
Bulk density of 60mm steel balls used in ball mills greater surface area and higher bulk density compared with balls of similar mass and size and 9 higher bulk density than steel balls or 12 higher than cast balls as a result for a given charge volume about 25 more grinding media charge 1 is the standard bond ball mill charge condition.

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 bulk density of a new rod charge is about 6.25 t/m 3. With time due to wear the bulk density drops. The larger the mill diameter the greater is the lowering of the bulk density. For example, the bulk density of worn rods after a specific time of grinding would be 5.8 t/m 3 for a 0.91 m diameter mill.
