A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing ¼ inch (6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns). In order to determine the power requirement, the steps ...
to mill aluminium, at least to the mesh sizes of a typical flake aluminium. In addition, I hoped that the results would provide some kind of indication of the validity, or otherwise, of this statement. Method The ball mill that I used has a jar 12 cm long, with an internal diameter of 12 cm, fitted with two 1 cm lifter bars.
The grinding process of the ball mill is an essential operation in metallurgical concentration plants. Generally, the model of the process is established as a multivariable system characterized with strong coupling and time delay. In previous research, a two-input-two-output model was applied to describe the system, in which some key indicators of the process …
1.Aaluminum Ash Ball Mill are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. 2.To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced.

process grinds the powder materials by impact/collision & attrition. • Milling can be dry milling or wet milling. In dry milling, about 25 vol% of powder is added along with about 1 wt% of a lubricant such as stearic or oleic acid. For wet milling, 30-40 vol% of powder with 1 wt% of dispersing agent such as water, alcohol or hexane is employed.
