ore wet ball mill use

Ball mill - Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steelballs. An internal cascading effect reduces the material to a fine powder. Industrial ball mills can operate continuously, fed at one end and discharged at the other e

Wet Grinding VS Dry Ball Mill Grinding - 911 Metallurgist

03/07/2017  In wet grinding the heavy ore charge in the mill would give a closed-circuit product with the minimum amount of coarse particles, but in grinding the advantage would be in favor of the small ore charge. Hence, it is seen that the writer who said that “the median diameter of the circulating load is larger when grinding wet than when grinding dry” did not realize that the median diameter might depend on the amount of ore in the mill.

Common Basic Formulas for Mineral Processing

20/03/2016  Formula (5) is used in making tabulations for mill use. As used in these formulas the specific gravity of the ore is obtained simply by weighing a liter of mill pulp, then drying and weighing the ore. With these two weights formula (2) may be used to obtain K, and then formula (1) to convert to S, the specific gravity. A volumetric flask of one liter capacity provides the necessary accuracy. In laboratory work the ore should be ground wet
