Ball Mill - an overview | ScienceDirect Topics

Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel.

Mill (grinding) - Wikipedia

Like ball mills, grinding (steel) balls or pebbles are often added to stirred mills to help grind ore, however these mills contain a large screw mounted vertically to lift and grind material. In tower mills, there is no cascading action as in standard grinding mills. Stirred mills are also common for mixing quicklime (CaO) into a lime slurry.

The mixture of ore and water is further broken up in two ball mills, which are like a rod mill except steel balls are used instead of rods. The slurry of finely ground ore that emerges from the final ball mill contains particles about 0.01 in (0.25 mm) in diameter.

Mount Isa Copper Mine, Queensland, Australia

Ore processing. The copper concentrator was rebuilt in 1973, with rod and ball milling and three-stage flotation, to supply the roaster and conventional blister copper smelter on site. In 1981, Mount Isa commenced anode casting as well. In 1988-1989, two 6.4MW AG/SAG grinding mills replaced the rod and ball mills at a cost of A$35m.
