Aug 11, 2018 There is the temptation, held by some, to open up the pebble ports to, say, 75-90 mm from 50-65 mm. Also, any increase in the nominal aperture of pebble ports automatically alters the power split between primary and secondary mills and places a heavier load on the secondary mill to the point where:

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

Iron Ore on a conveyor [image 135-1-1] Digging ore from the earth is only half the battle. Often just as challenging and costly is the processing of the ore, which takes place in mills, smelters and refineries. Processing requires crushing and grinding to liberate the minerals. After liberation, separation processes are used to concentrate the
