The F.C. Bond Ball Mill is a small universal laboratory mill used in calculating the ... made in the Bico Mill rurming at 70 revolutions per minute with a charge of285 iron balls ranging in ..... EriDdirg an ore from 80 p.r cent-l4 mesh to 80 per cent-.
In the test of iron tailings with different origins the ITPs were ground to an SSA of 480 ± 20 m 2 /kg by ball mill grinding. The SSA of PC and FA was 341 m 2 /kg and 254 m 2 /kg respectively. The particle size distributions are shown in Fig. 3 as measured by a laser diffraction instrument 4BT-9300ST .
The ball mill then grinds the feed to a fine powder. The fine powder is then sent to a separator which separates fine and coarse product. The latter is sent to the mill inlet for regrinding. The final product is stored in concrete silos as cement. Cement is so fine that 1 pound of cement contains 150 billion grains. 6. Final Product
Most useful metal in the world Iron is extracted from iron ore. It is the rock from which metallic iron can be economically extracted. Iron ore is a mineral substance which when heated in the presence of a reductant will yield metallic iron Fe . The iron ore usually very rich in iron oxides Fe3O4 and Fe2O3 .
