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 …

The modifications include ball mills and vertical mills as well as preheater, kiln and cooler upgrades. ... The tertiary air duct enters the calciner without enlargement of the flow area i.e. with the full velocity. The tertiary air enters the mixing chamber fully tangential.

The change from a SAG mill to an HPGR in primary grinding results in a lower overall power consumption the comminution circuit. In comparison to using staged crushing as ball mill feed prepara-tion, replacing the tertiary circuit with an HPGR frees up ball mill capacity (or reduces the size of the ball mills and grinding media consumption).

Traditionally ball and planetary ball mills are used. However, these mills have weaknesses; for example, there is extensive wear of grinding parts of the mills, as the materials are exposed to intense heat, etc. Grinding by collision is considered a more effective way to refine brittle materials and an alternative for the mills that produce ...

Ball mills are the most commonly used piece of equipment for milling. However, vibratory mills, attrition mills, and fluid energy mills also are used. Crushing and grinding typically are dry processes; milling may be a wet or dry process. In wet milling, water or alcohol commonly is used as the milling liquid.

Freeport McMoRan's (Freeport) Cerro Verde operation was a ground-breaking installation in that a combination of secondary' crushing (using MP1000s), tertiary crushing using HPGRs, and screens replaced what would have been more typically been a large SAG mill feeding a multiple ball-mill circuit (Vanderbeek, 2006).
