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.

Nkwanyana and Loveday (2017) used batch grinding experiments in a 0.6 m diameter mill to test partial replacement of steel balls (37.5 mm) for secondary grinding, by partly rounded pebbles (19–75 mm) from a SAG mill. At the optimum pebble content of 25% by volume, a 25% saving in steel ball consumption and a 15% saving in energy consumption

2016-6-14 · Considering that worn balls in an industrial mill charge constitute about 15 to 40 percent and that the highest difference in breakage rate observed being nine percent for purely one shape charge; it is very doubtful whether it is worthwhile in attempting to develop techniques for removing worn balls from the mill.

Ball-mill Static charge volume: 33%: Silica sand: Steel balls – Composite milling 25/75 by volume pebble/ball mixture has the best performance in milling (Nkwanyana and Loveday, 2018) −75.00 + 13.20 <19.00: Pebbles −75.00 + 13.20: Ball-mill charge volume: 20–23%: Phosphate: Cylpebs: 600–700: More surface area would provide more

The effects of percent solids, mill loading, and grinding time on product size distribution and ball wear were studied in a laboratory ball mill for a taconite ore. Mild steel balls and HCLA steel balls were used to examine the role that ball hardness play in grinding. Net production of −44-µm (−325-mesh) material reached maximum at 70% solids, whereas the ball wear decreased as pulp

2020-6-14 · i don't know what size ball mill you have but, if you take the time to do the simple math of approximate mill volume before VS after new liners are installed, you will see what Todd is referring to. typically, you stop loading balls in your mill about 1 week before the reline job. it helps avoid/reduce full ball rejection on restart.
