Using a 5 litre batch mill an experimental programme was designed to study the comminution characteristics of the stirred mill. A factorial design was prepared with the following parameters which influence grinding in the stirred ball mill pulp density pin tip velocity and ball density and size. The energy required for grinding the chromite .

view of grinding and comminution in ball mill. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter Figure 8.11 . The feed can be dry with less than 3 moisture to minimize ball

Sep 25 2009 The principle was tested on the planetary ball mill and the horizontal laboratory ball mill and according to the results obtained it can be concluded that the proposed methodology can be useful for the evaluation of the selection function during batch comminution in different mills.

Should a grinding media shortage arise know that you have options and that you can tailor your comminution circuit operation. To learn out more about operating milling circuits with reduced or no grinding media as AG-ball mills or single-stage AG mills contact Grant Ballantyne Rajiv Chandramohan or Matt Pyle.

May 01 1991 1 Overload in overflow ball mills is due to the approach to a critical axial flow velocity for pulp of 0.072 ms. 2 While so far important only with 5.0 and 5.5 m diameter mills it should be found with smaller mills in combinations of very high circulating loads excessive LD ratios very soft ores or coarse grinds. 3. A proper balancing of lower Lf and higher F values

If a ball mill uses water during grinding it is a wet mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. Ball mills may be primary or secondary grinders.
