The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 5-10 cm in diameter but gradually wear out. Grinding is always carried out under wet conditions, with about 70% solid mixture in water. This procedure maximizes ore production and minimizes power consumption. Contact Us Now

2: For concentration of ferromagnetic minerals increasing ore grades and recovery rates. 3: Used before a High Magnetism Separator to remove ferromagnetic minerals from ore and prevent magnetic clogging. 4: Removing iron from non-magnetic minerals or materials. 5: Recovering iron from river and sea sand. 6: Removing iron from wet slurry.

The wet pan mill is named by the diameter of roller. Φ1300,Φ 1350,Φ 1400,Φ 1500,Φ 1600 is suitable for selection of iron ore, molybdenum ore,lead ore,zinc ore, antimony ore and so on. Φ 850, Φ 900, Φ 1000,Φ 1100,Φ 1200 is suitable for selection of gold ore. As their small investment, high yield, the production cost is…

The wet grinding of iron ore powder was investigated using a stirred media mill. In this study, the fitting degree of four cumulative undersize distribution functions was compared and the parameters of the four functions were discussed.

The metallization of iron in the solid state reduced sample generally increases by increasing the wet grinding time. The metallisation of iron with grinding can reach 87.32% when the wet grinding time is 60 min, whereas the content of FeO decreased from 10.62% to 5.28% by increasing time of grinding. (3)

The choice between wet and dry milling is, in general, unimportant in small-scale milling but is a major technical problem when large-scale milling in the metallurgical industries is involved. On purely mechanical grounds it is difficult to see any great difference in fundamental principles between wet and dry milling, since dry milling may be regarded as wet milling with a …
